I am thinking of purchasing a TOM-TOM3 GPS system has anyone got any experience using the BT ?. Is it as Temperamental as the headset. Would it be better to use a wired GPS.
Thanks
I have wired and bluetooth GPS and would say that most of the time I use the wired GPS because I use it mainly in the car and it charges my MDAIII at the same time.
tomtom 3 and BT is fine on my MDAIII
No problems here with the bluetooth connection to tomtom's own GPS.
Never lost the connection.
Left the MDA's BT on one night and woke up to an empty battery and no data though!
I am using BT TomTom no problems at all with staying connected.. you can get them for under £100 on ebay now, best gadget i've got, except the IIs of course.

I've been using a TOMTOM BT GPS for a few weeks now and had no problems at all infact as with another post its my best purchase so far.
I have just got my XDA IIs, I have Tomtom 2 (Wired version), is there a cable kit that will allow me to use my existing Tomtom with the XDA IIs?
If so can someone tell me what the part number is and who stocks it?
I've got a powered holder in my car, powers the XDAIIs and the GPS antenna (Holux 210 I think!). The holder also feeds Tx & Rx to the XDA on serial port 1.
I've also used the holder to just power the XDA and BT antenna and it also works fine.
Got it from www.nemesisgb.com - they are the importers
The actual product can be found here
www.brodit.com and type in 970612 into the quicksearch box on the right hand side

I have used ToTom 3 with their branded BT GPS for ages now and it works a treat, best accessory I had for my XDA II and it works just as well with my XDA IIs

Thanks for the reply, sorry been a long time before I got a chance to read it, busy christmas. That sounds like just what I need, I have a couple of further questions though.
1. The connections it talks about is a PS2-cable with RX, TX, 5V is this the connection that looks like an RJ11 modem cable or is this the same as a PS2 connection for a PC keyboard/mouse? My cable looks like a modem style RJ11 connector.
2. Does is come with a windscreen suction mount, I couldn't see it in the description and there were no specific pictures?

The connection I've got is a PS2 like a Mouse/keyboard.
The antenna you have sounds like a Leadtek which is branded as TomTom - looks like a flat silver square?
As it happens I now work for Nemesis and we are working on a connector to connect your antenna to the holder we supply.
2. Does is come with a windscreen suction mount, I couldn't see it in the description and there were no specific pictures?

You can get a bracket that fits your vehicle and then you screw the holder to the bracket.
There is another option though.
If you have a lead that plugs into the cigar lighter, powers the antenna and the XDA (I found one at www.handnav.co.uk ) then you can do something different.
Get a bracket for your car
Get holder number 849612 from Brodit
Use the lead to power the holder and the antenna
I have attached pictures of the above config for a XDAII as I had to use the IIs to take the pictures!!!
Hope this helps
..Spence
Thanks again, how soon do you think Nemesis will have a compatible cradle or adapter ready to market?
It might be worth waiting depending on time scales involved?
Or maybe the Tomtom cable, the 1 at the bottom of the pics laid out like a W is already ok, I have one like this to fit my HP Jornada 545 (an old relic from Aug 2000). This cable looks a lot like the cable shown in your pic except for the PDA end, which splits into 2, 1 is for data the other for power. The power part looks similar to a Sony Ericsson telephone charger cable, so again I'm not sure if this will suffice.
I wish there was a shop I could just go into with these things, as it all seems harder to explain when I don't know what all the bits are called. I can't really expect ppl to find a peg for a hole if I can't tell them what shape the hole is, and with hole on my PDA and my GPS receiver it gets doubly confusing!!!!
I'm using Navman 4100 BT GPS, the singal is great and never drop BT connection. It comes with a Y cable that can charge both the IIs and Navman.
But check out the all-in-one solution from Brando... Cheapest alternative I've ever seen.... http://shop.brando.com.hk/universalgpscarholder.php

Anyone know where I can get one of these in the UK?
I am attempting to house an i-mate PDA2 in a custom enclosure (for a product that we make). I want to modify the 22 pin connector on the sync/power cable but I cannot find a pinout.
I need a picture or diagram of the 3, or is it 4, rows of pins with pin numbers, pin function and connector wiring (jumpers, etc.)
Anyone know where I might find this?
Before you get crushed by the "rtfm" type posts, I humbly direct your attention to the "connectors" link on the front page of this site, which will lead you to: http://wiki.xda-developers.com/wiki/Connectors. It's an extremely useful page!
OK, I told you so now you tell me; what're you guys making?!
I did check out the "connectors" page and it is helpful.
However, what I am looking for are details of the inside of the cable connector. I took one of these connectors apart and it's not the easiest thing in the world to figure out which pin goes to which on the PDA side or what the number system is.
So, it would be very helpful to know if someone has already gone through the unravelling.
In a nutshell, our company has developed a technology that uses ultrasonics to measure load in bolts both during and after tightening. The PDA is the platform for the controller of the tightening and inspection tools.
Sorry, I assumed that you'd not looked at the connectors page because I used it to figure out (I think) what it is you're after when I was trying to make my own sync/charge/gps connector.
If this is something that you can't resolve with a multimeter, then I guess you must be looking at an interesting connector! I'd suggest posting a couple of pics of the connector with it's top off lined up with the phone's socket. That'll make it easier to figure out what's what!
The load detector sounds cool, I'd love to see a screenshot if you've got one.
Yes, it can be resolved with a multimeter - I was just looking for the lazy way out!
I have attached a photo of the prototype unit - not the most professional representation, but a decent one nonetheless.
That looks cool! I love it when people *really* use these things.
If you open the connector up and see 2 (staggered) rows of tiny, really hard to solder :lol: pins, pin 1 (left side of the phone connector if you hold it bottom towards you, screen up) is the bottom left pin.
_| | | | | | | | | | |

^ bottom left is pin 1. Hope this helps, sorry I had to bath the baby earlier and was typing whilst holding a somewhat sticky little girl
Thank you!
Subject: PDA2 sync/power cable connector pinout
On this thread, I was thinking of using the desktop cradle as the base for a mobile mount.
But the pin-outs for the PDA2k are not easily found.
The connector link now appears to be at:
http://wiki.xda-developers.com/index.php?pagename=Connectors
This page seems only to refer to the Wallaby and the Himalaya.
Is there a specific page for the PDA2k or does anyone know if the pin-outs of the 22 pin connector are the same for the Wallaby/Himalaya as they are for the PDA2k?
-I found elsewhere that Pin 19 was different.
Are there any other differences?
Also somewhere amongst the threads there was a mention of the pin-outs of the 2.5mm audio out /mic in was different or was it the switch on the hands free headset?
I have trawlled the site and it has eluded me so far for a consiolidated posting on the connectors for the PDA2k.
Can anyone point me in the right direction?
Perhaps I am just deluding myself
Thanks in advance
If you lost your marbles, would you know where to find them?
harrier mounts and connectors
I wouldn't use the desk cradle to make a car mount. IMO the car mount from Clicon (www.clicon.com.au) is better mechanically than the desk cradle, and already suited to vehicle mounting
There are a number of variants of their kits, but not many that suit my pda2k-evdo. The ones that do suit are:
- plain cradle with no connectors, but leaving the pda2k connector exposed and accessible
- plain cradle with "passthrough" connector - so connect your own charger etc to the bottom of it. Note that this passthrough doesn't support the two lugs that some pda2k plugs have (eg the charging dongle that came with the pda2k-evdo)
- cradle with lighter-socket charger. The charger part is actually removeable; they've just screwed the car charger to the cradle.
The lighter-socket charger mentioned above has a small board inside the connector with Tx and Rx holes labelled. It looks like it was designed for making a serial+charge adaptor.
I have a separate RS232+charger adaptor cable ("suits XDA IIs") which looks like it's charging, but really just keeps the screen on and runs down the battery quicker. It turns out it only has one V+ and one Gnd pin connected, as opposed to 3 of each listed on the Connector page on this site. Makes me wonder whether the 3 pins for V+ actually all have the same function. Time to mod the connector...
Gregnash,
I agree with your summary,
and I have looked at the available in car cradles/holders.
I have already ported a XDA1 cradel with audio/mic,USB and power to see if the connections can be done successfully.
All worked except for the mic as I need to find a 4 polo 2.5mm panel socket so that it switches on hook.(this I assume is pin 19)
You are right, by itself the Harrier cradle does not securely hold the pda in place as there is lateral movement.
What I am trying to achieve is a "all in one" in car cradle/holder.
I have sucessfully mounted a NOKIA passive anennae connector to a stand alone generic brand pda holder.
This as you said allows the connector to be exposed for charging.
I have used this method with a 9db external (old analogue antenna-funny that, you can use them for CDMA) antenna or a 9 db through glass antenna.
Currently the system is clumsy as also I run a bluetooth external GPS and route the audio from the 2.5mm socket to the cassette player adapter.
-(no audio IN in this car radio)
What I was hoping to do was to incorporate the Nokia Passive antenna coupler at the rear of the Harrier cradle which would put slight pressure in the forwards direction to both make an antenna connection and more secure and stop the Harrier from moving.
(Another flash idea is to strip the inductance plate from the coupler and mount a antenna cable socket on the coupler face so that it aligns with the antenna out from the Harrier)
With the audio out /mic in and charge through this connector , I am hoping to eliminate all of the wiring as I can conceal the wiring back inside the dash.
The only other thing is the on hook switch for receiving calls.
As you can probably guess I probably have too much spare time.
Perhaps Bluetooth In car kit will by-pass the need for the physical connectors as it is software driven.
But I have heard of so many bad reports of BT connecting to the phone that it appears to be pot luck if I find one that works.
What about this arrangement:
1. Harrier cradle -with antenna coupler if secure,
2. bluetooth in car (cigarette lighter style) hands free-Blue Ant etc,
3. audio out from cradle to radio ( for GPS instructions and playing mp3 from Harrier) freq transmitter(powered externally).
4. bluetooth GPS external antenna
mmmm..... maybe a bit of an ask but it does allow a "drop on cradle ,push forwards to engage antenna and forget" action.
Maybe I am off with the fairies, what do you think?
Any comments would be appreciated.
For antenna supplies you can try this site http://www.wpsantennas.com/ basically I think it would boost reception back to 3 watts. 3 watts is the same wattage as the old car mounted mobile phones. Mobile phones operate on 0.5 watts. No wonder our reception sucks in so many places.
Hook the antenna into a car cradle and some type of handsfreee switch for the radio, and you have a very powerful, very mobile 3 watt mobile phone with great reception.. if you got carried away you could even connect your car to the ppc and moniter engine, fuel, etc. Plus a GPS.. and oh the possibilties are endless.
Johnno's ambitious car kit
Yeah, I think you do have too much time on your hands
Sounds like a plan, though, and I'd like to know if you make it all work. The antenna couplers I've seen take a bit too much force for a "drop in, push back" arrangement, but one designed for a different phone may do the trick if it fits.
btw, my interest in serial is for wired GPS and to talk to the engine management computer (not at the same time, or one will have to be bluetooth). Even better if they can be powered from the same cable.
dougnet
Thanks for the link.
I actually had thought of this proposal.
I actually contacted tht crowd (amongst others) about two months ago as I was thinking the same as you.
They answered that they are not allowed to export GSM or CDMA amplifiers to Australia.
I think it might be that new "Free Trade Agreement and respecting our telcos" we now have with the US where things are not really "FREE".
Probabably if I asked 12 months ago it might not have been a problem.
Nice products.
Trouble with Antenna couplers , is that you lose at least 1.2db + in the cconnection.
You you really need a grunty antenna or output.
".. if you got carried away you could even connect your car to the ppc and moniter engine, fuel, etc. Plus a GPS.. and oh the possibilties are endless. "
Now I have an automatic car so rev monitoring would certainly be overkill.
I get your drift, though thanks for the input.
gregnash
I will have to see how much force is needed to engage the pda.
Don't forget that at least the same force will be needed to disengage it as well.
Mmmm...good point, this means seeing whether a panel mount socket is available in this cofig.
Wouldn't have a clue who might sell panel mount sockets suitable for the Harrier/Blue Angel?
I am not sure how a cable termination would cope with the forces needed.
The fixing method would have to be substantial.
Serial connections to the car comp?
You would probably need to hack the code to get access to it I suppose?
But if you could tap into the on-board engine management computer, then you could change the air to fuel ratio at the injectors and lots of other cool things like disengage my engine cut-out at 190k/per hour and have some real fun!!!
Not much fun at 190K/h and the engine stops-no brakes, no steer!!!
Must be for the rev heads-NOT ME!
I will investigate the force on the antenna connector to see if this is feasable to mount.
I will let you know what I find.
Hi all.
Thanks for the encouragement.
Well life is full of compromises!
So long as you do not require audio output and you are happy with the Harriers speakerphone volume, I think I have a home solution for the uninitiated.
1. I have a "generic brand mobile phone holder-one of those adjustable in width ones- full width just held the Harrier nice and snug.
2. To this I mounted at the bottom (after removing the locking latches)
a USB car charger cable -with no modifications.
-Actually I pop rivetted the backing shell to the holder.
3. I then mounted a Nokia a passive antenna coupler and sculptured the holder-so that it fits at the right height and to the left of the Harrier.(where the antennae is on the Harrier)
4. I then mounted the holder onto the dash of the car (my choice as I put it though a removable panel where a digital clock is fitted in an other model, and passed the antenna cable,and the charger cable to a cavity in the dash.
5. Here I supplied a cigarette socket with 12 volts and connected the charger cable.
What I ended up with was a car mount that was a "drop in" style that
was easy to build without any fiddly soldering of connector pins.
I actually did make it with USB and audio out but these were surperflous as at the moment I do not have an audio in for my car radio or an amp to drive it.
But I just wanted to see if it could be done.
This is why in the picture you can see electrical tape around the cabling.
(This is because I had USB,Audio out and Car charger cable.)
Once you have this type of holder, it is not hard to get a new holder and move only the antenna coupler across ( I would think that the new connector would be different from the Harrier)when you upgrade to a new PDA.
In summary:
Compromise 1.
1.2db loss at antenna coupler-using 9db external antennae so I can live with that.- but no nasty "push to connect" hassles.
Compromise 2.
Audio out does work but the level is so low that it needs good amplification , this I will not follow up until I get a car radio with audio in.
Rely on Speakerphone fore the time being.
I hope this is of help to those thinking of this kind of project.
I hope the picture is reasonably self explanitary.
If you have any questions just let me know.
Hi all, hoping somebody can tell me if here is a difference in the connectors at the bottom of these 2 phones??? The reason I ask is because I have come into possession of a Professional GPS Carkit for a XDA2 whic I have modified cosmeticly to accomodate the XDA. All parts other than sound and microphone are working. I would appreciate any guidance some of those in the know would be forthcoming with.........I have put my phone back to standard with the rom etc to be sure the upgrading of it had no adverse affect, so it is exactly as I bought it now, and still doesn't work properly
Check the wiki for the connector pinouts to confirm they are the same. They only device using a slightly different 22 pin connector is the blueangel with two ridges in the sleeve.
Richard
my xda1 got stolen and i could use both the cradle (xda1 cradle is soooo much better then xda2's)
and charger connector (of cause)
and headset
ok......a little progress nowhere really but, anyone got ideas on this........I pulled the control panel apart on the car kit, i have found that if i put the phone in the cradle whilst on a call and the sound comes through the speaker when it beeps to say it is in the cradle???? Upon checking it further, the control panel clicks, i presume that it 'opens' the connection to the speaker, but will close the connection and not reopen it if i make a call from the cradle tus rendering the speaker an the mic inoperative. I have found that the 'car on' wire appears to go through a resistor once on the board so could this be cutting down the input too much for the signal from an xad1??? Anyone with some technical knowledge on this would be really helpful. Thanks in advance
Hi Guys,
I have just got the fantastic little E72 and it is great in almost every way. I want to be able to use my Shure headset with it so I need the adaptor that everyone else wants to find it seems. I have a HTC adaptor but it will not fit into the socket. The socket on my E72 has 5 pin holes and both sides of the interface are curved. The HTC adaptor has one curved side and a straight side so it will not fit in. The E72 does use the usb connection for its headset and audio output but when I did find a Samsung adaptor with both sides curved that did fit into the phone socket it still outputted the music to the external speaker so I am at a loss. There are, therefore, different types of mini usb connectors. Can someone tell me the exact spec of this one fitted to the E72 and possibly where I might get an adaptor that will work??
Much appreciate the help with this.
usb cant be changed to 3.5mm or any type of audio
the reason the htc one dont work is the same reason it dont fit
it have extre connectors which carry analog audio
normal miniusb is a serial digital interface which dont carry analog audio
and usb headsets for pc are really external audiocards which make the serial digital data to analog audio
and that require the ability to usbHost which few pda's support
Many thanks for the explanation. However, my phone came with a stereo headset with mic. I currently use this for listening to music but the quality is not good. Does this not mean then that I should be able to get analogue signal from it??
Please forgive my ignorance; I am learning!!
it all comes down to where you connect your headset
if it's the miniusb port benQ got an extention of miniUSB like htc's extusb
if it's a 2.5mm minijack like older htc devices used you can get a conveter to 3.5mm
The only port on the Benq E72 is the mini USB one. There are no other jacks. The problem is that both sides of the metal housing within this are curved so the HTC one (with one side of the miniUSB adaptor straight) wilkl not fit. I did manage to find and buy an adaptor that was branded Samsung and when I fitted it into the miniUSB socket on the phone it would not work. The music continued to play through the rear speaker even though the adaptor was connected. My supplied headset connects to the phone through the same miniUSB paor but again the metal housing of the miniUSB jack is curved at both sides. I hope this explains better.
as i said then miniUSb should not alow audio at all on the device
and htc use extusb which have more legs then miniusb so if it dont fit
it should not be because of any curves
does your benq device not alow headsets at all ?
if it does how are they connected?
The only connector on the Benq E72 is the miniUSB port. In the attached pic you will see the connector for the wired head set on the left and the miniUSB to standard USB for connection to the PC on the right. I looked inside the silver housing of the connectors on both cables and they seem to have 5 pins along the top (widest) part with the main section being hollow. Now the miniUSB housing on the actual phone does have a plastic inside with 5 pins and , I guess, more connectors along the top of this for the 2 cables. I am to assume that the plastic insert in the phone itsaelf is for the electric charger. There is nothing more that I can give you except to say again that the miniUSB is the only connector on the phone.
if it support headsets connected to the usb connector it must be using some sort
of special usb connector like htc's extusb
i would look at their site if they sell converters
Thanks, as I said the only way to connect the headset is by the miniUSB port so it must support audio. The issue is that the HTC miniUSb headset has a curved side and a straight side so it will not physically fit into the Benq E72 connector. I did get my hands on a philips miniUSB that did fit into the socket on my phone but the music still outputted to the rear speaker of the phone. So, my question is, is there different types of miniUSB wired internals? It would seem so. And would anyone know which would work for the Benq E72 windows mobile poweredsmartphone?
@ 17-apg,
Sorry for this off-topic post. Im planning to buy benq e72 because my o2 xphone2 is too old. Can you please give brief review of the phone, as a user. Is it true that it is laggish? Thank you.

No problem ,,
I have the device for over 2 months now and like it a lot. Had a HTC S730 before which was thick and cumbersome and I didnt really need the keyboard. This phone, in contrast, is very light and thin. It runs WinMo 6.0 and I do not find it slower than the HTC in any way. On reflection maybe a little faster even. It is very competively priced as it includes bluetooth, quad band radio and wi-fi. The bluetooth also carries the A2DP functionality. The screen, whilst a little small at 2" is very bright and clear. The keypad has large buttons and is very tactile and positive when texting.There's a 2 meg camera included as well as the microSD slot with a max size of 2GB. You can, however, with software, increase this to the norm of 6GB which I have done. Also the rear speaker (built in) is a reasonable size and therefore can play a decent sound for music if you are travelling and in a hotel room for example. And finally, it has little important assets like the ability to turn on auto redial, a button on the left side which when pressed and held will open the text messaging in a send window. There is also the facility to adjust the screen brightness as well as an internet radio and ringtone editor. All in all, for the price, I definitely recommend this phone. I have bought four more since for friends of mine. They paid of course!!! Now all I need is the miniUSB to 3.5mm audio jack sob sob...
Can you tell if a lanyard can be linked to the device - and where? On all available photos on the net I have not seen any holes for fitting the lanyard to :-(
I am really tempted to get that one as well - escpecially as it is the ONLY (!) smartphone with only a normal keyboard that can use microSDHC cards (after installing updated drivers). They seem to double in size every year - and if the standard is fully supported 6 or 8GB (as reported sucesfully) should not be the limit.
Lanyard
Yes, you can connect a lanyard at the top of the phone. If you can see the top view of the device there is a little hole there. You simply slide off the back cover and fit the lanyard to the designated area on the main body of the deivce (very easily) and then slide the back cover on again.
Now we just need a cooked 6.1 rom for the device!!!
Thanks - I found a set of pictures at a Taiwan Review site (http://www.eprice.com.tw/mobile/talk/?prod_id=2621&tid=3430647&page=1&list_page=1) - this tells it as well
I was only looking for a small device that can read memory cards > 4GB and this is the one now. Otherwise my Tornado in the house of a Robbie still perfectly fits my need. I also tried WM6 and WM6.1 on that - but fell back to the original WM5 there.
Just can't wait to get it in my hands - it was really a bargain on ebay. Search for benq E72 there and you will see a guy in London selling refurbished E72 for just 69 GBP (9 of 21 left). I just could not resist for that price, sigh...
BTW - on topic: did anyone try the Motorola mini-USB connectors - for the Razor and alike?
I dont think so. DO you habve one that you coulkd try when you get the phone? If so, let us know here cause I would really like to use my own ear buds.
BTW I think you will love this phone! It really impresses me. And also Expansys anre selling brand new ones for about £90.00!!
Is there a WM6.1 for this? Thanks.
Benq E72
Not thatI am aware of. I know that another avid fan of the E72 has requested ROM cookers to try to come up with the 6.1 version bit I am not sure if anyone has taken up the challenge.
I hope that it will happen soon ...
I have received mine in the meantime, but the refurbished one was delivered with a non-fitting headset :-(
Well, it fits mechanically, but there is no sound at all. It looks like a cheap replica of a Motorola Stereo Headset - but also a normal Motorola does not work in this socket. So I am out of any possibility to measure the data of the socket to build an adapter. I complained at the dealer - hopefully there still is a working headset available!
Otherwise the device is nice - only English language installed though for menus and T9.
bye
tobbbie
With some help from Taiwan - the USB wiring for the headset is identified, see my blog article at http://tobbbie-benq-e72.blogspot.com/2008/12/hacking-usb-headset-connector.html for more details. The main information is:
....So the final result is then for the numbered pins of the USB connector (1-5):
Must be connected with a resistor less than 200 kOhms to ground (pin 5). The voltage will rise briefly to battery level but then drop back to 0,16 V to stay there. I suspect that accepting calls with the headset button will introduce new functionality here...
Speaker channel (l,r not checked, source indicates right here) - must be connected to a speaker or a pulldown resistor at device-headset connection time.
Speaker channel (l,r not checked, source indicates left here)
Microphone channel (checked to work with Audionotes)
Grounds
So luckily no complicated electronics - get your soldering irons ready!
BTW: have still not received the original headset :-(
Hello,
i want to connect external wifi antenna to S620 and i need some small help with that.
I dismantled the phone and removed shields from all ICs.
On picture 2 and 3 are Texas Instruments WiFi chips.
On picture 1 is other side of the board, with some metal piece and connector, which might be external wifi connector.
The connector is at opposite side in left bottom corner if you look at image 2, between PASS sticker and mounting hole, at the corner of large PCB ground pole.
Is that metal piece integrated antenna?
That connector is probably not U.FL.
Anyone know what type of connector is that?
Thanks.
Not sure but follow the link below for the service manual, it may give you some insight:
http://forum.xda-developers.com/showthread.php?t=402998&highlight=service+manual
if you managed tu connect it, let us know everything...
hope you can do it succesfully!!!
Ok, so i looked at the service manual, the connector is diagnostic (RF measurement) type, with switch.
MM8430-2600RA1
Probably will be in all HTC devices. So i will try to search on the forum, if anybody done this on different phone.
See page 9 and 10 for switch schematics and pinout
http://www.murata.com/catalog/o30e8.pdf
There are "probe" cables for it, but the probe connector is too big to hide under the cover.
I have a friend with experience with SMD, so i asked him if he can desolder it and solder pigtail with RSMA.
Cable can be taken out of the phone by using free space around hole which covers the GSM antenna connector.
I verified that by putting the cable in and closing the phone.
I also tried to hold stripped cable on the connector, with attached directional antenna and i picked up the APs in that direction, so it is working. (and really well)
The problem is that ground poles of the connector maybe connects ground to the power button, so after desoldering, it might not be possible to turn it on...
The safe way can be removing that piece of metal (yes, it is wifi antenna) and solder pigtail instead of it.
It should be simple, because under it are only two "paths" in PCB.
However, the best way is probably to solder it on opposite side, there is a PCB path from Wifi chips, going through the PCB, ending on middle pin of the connector.
But that cannot be done, because there is no way how to get the cable out of the phone.
I still prefer desoldering the connector, because it is placed "before" the antenna, so connecting it there would give a bit better results.
Edit: i searched the forum a bit, but all i found is service manual for Diamond, which seems to have U.FL connector. But i will not buy it because of that, only maybe when it will cost 80 USD like S620.
