External aerial

Can anyone recommend a compatible GSM aerial I can attach to the JJ
It has two aerial connections, one for GSM and one for 3G.
At home I have poor GSM reception and no 3G and the JJ seems far worse at picking up a signal here compared to my Sony K750i
Or can someone tell me the connection type used for GSM on the JJ so I can do some research myself via Google
I have a similar problem and would also like to hear of an ariel to use at home.

wizard antenna mod

hi guys
well i have a question... I was digging out whole day the net for info about any mod for the wizard antenna mod...
I own CIngular 8125 aka HTC Wizard 100, and since I have week wifi signal i thought id get better reception..
so i found some sites including instruction here also but i went for this mod
here http://tinyurl.com/y2gke3 exactly i made the same thing as shown here http://tinyurl.com/v2oxv I cut a small piece of antenna between 2 pins rely..
so, actually nothing happened with my GSM signal, it was same as before, but i found out that my wifi signal dropped a bit, which I wanted to increase...
so, i thought for making this mod here http://tinyurl.com/wq8k2 and id like to know if it gets any better wifi signal strenght...
next thing id like to know, is the issue with the antenna... is the same antenna used for GSM and wifi or what? did anyone managed to get any wifi antenna connection on PCB of a wizard so it can be attached a better antena?
if I connect an external antenna to my wizard, will the wifi signal get any better? the pcb looks similar to this picture http://tinyurl.com/y5p7yh and on the left from sd card is the external link...
is there any possibility to get better wifi strength using any kind of hardware mod? smthg like this for axim http://tinyurl.com/sbf3v so i can connect any wifi antenna...
well guys, i was a bit large writing this post but id reeli want to know of theres any possibility to get better wifi signal...

Phone signal

Please help! I bought an unlocked SPV M3100 on ebay. Everything works fine, but the phone signal (and gprs) is rubbish. If I'm in an area with a strong signal, it's fine. If I lose my signal completely, and put my sim card into my old phone, (xda mini s) the signal is fine. I was told to change the phone settings to GSM and to upgrade the radio to version 1.41.00.10. I've done both, but no change. My ROM version is Pro Black 2.5. Any suggestions? I'd hate to have to resell the phone. Aside from the signal, it's fantastic!
Most likely either a) you are in an area with a crap phone signal or b) Now you know why it was sold off on e-bay....
Personally I would have said stick with radio 1.40, as 1.41 seems to vary greatly in how well it works from place to place. Read through its thread and you will see what I mean.
Setting the phone to GSM is more of a battery saving thing than than helping the phone signal, and it means that if you have HSDPA enabled on your account, it wont switch to it when available so you wont see faster speeds.
NB. But do please read everything carefully if you decide to try a downgrade to 1.40 though.
Signal
Thanks for the quick post. I'm sure that I don't have a crap signal area because my old phone works fine in the same area. When I bought the phone it was new (just opened to unlock and upgrade) and it works fine in certain locations, so I don't think it's defective. I'll try the 1.40 radio and see how that works. Many thanks, Jon

I have the same problem with Hermes...
Has tried all versions of Radio & ROMs.
Does not help... The Signal still vanishes
Have you tried using the GSM switcher to see how it works on GSM?
Hope you get it worked out.

m3100 signal
Thanks for your replies. I tried the GSM, and I've changed the radio to 1.40. I'm still getting no signal in areas where I get a decent signal from my XDA Mini S. If you have any other ideas, I'd really appreciate it. Otherwise, I guess it goes back on ebay...

hi every one
i also had the same problem. i flashed my prophet with every version of windows and gsm rom but it didnt work. then i opened the prophet and straightened the antena connectors and then packed it, it worked full signals.
so check your antena connectors inside your phone.

Motherboard, mainboard, logic board main parts, where is the radio (network) ?

Hello,
Can someone tell me where the radio is located in the motherboard, I mean the radio to make and receive calls, 2G, 3G, 4G, LTE.
Is it together with the processor? That rings a bell but I am not sure. Please see attached a couple of photos from the motherboard, front and back, in case you want to use them to point it to me.
Thanks
