Who is Using their Diamond in the US on ATT?

I am starting this thread because there are a few of us out there who are using our Diamonds in the USA. As such who has the 3G working with ATT? What Radio are you using? What cool cabs are you using? Cheers.

I started this 2 weeks ago
I have a Diamond on At&t network......ALL IS GOOD.....EVERYTHING!!!!!!
Peace
Mike

I just got mine, and it is working on phone on AT&T ... but I haven't tried data connections yet. (WiFi works great.)
(The thing is so feature-stuffed it's hard to take it all in!)
I'm trying to understand how to enable the 850Mhz band, which involves flashing a new ROM, I think. Right now it has 1.93.456.2 WWE
My understanding is that it wont do 3G in the USA, even with a new ROM.

That is correct. GSM 850/1900 work just fine, EDGE works. No 3G :-(

I have a diamond on AT&T and all is good except 3G data is not working only Edge. To enable the 850Mhz band you will need to flash the 0.5 Radio. Of course you also use any ROM of your choice but the only Radio that enables the 850Mhz band for now is the 0.5.
Hopefully someone will unlock the 850 3G for good.

im on att as well, im thinking of going diamond or touch pro. The 3g being activated for data is critical for me. Does anyone know for sure if the limitation is only software based, or is there hardware differences?

No confirmation either way on this. It's been asked (and awaiting an answer) by lots of people. It's the "$64K question".
So, right now, there are 2 Radio ROMs that support 850 Edge/GPRS/Voice. And 0 Radio ROMs that have been confirmed to support 850 3G.
I think we're all still also waiting for the Telstra Radio ROM dump that works on Telstra's NextG/3G network. Supposedly some "custom" .06 radio. Need to wait and see.
Just a gentle reminder: don't get Radio ROMs mixed up with the other OS/software ROMs. THey are independent of eachother. It's the Radio ROM that is needed that might make 850 3G a possibility.

I'm on AT&T in so cal and once I flashed the radio to .05 my edge reception was much better and more consistent. Still waiting on Telstra radio to see if 3g works

I have the 0.5 radio, and EDGE is working just fine for me in Pasadena, CA.
Just how much faster would 3G be as compared to EDGE, if it was enabled in the phone?
Is there a way to find out what frequency the radio is currently operating at?

My friend, not only 3G is ages faster than egde but also the quality of the calls are crip clear since the network/phone when switched to 3G will use a different codec when making a call thus calls are clear...

Hey guys, would you please be so kind and post in the appropriate categories. We are talking here about ROM development. So the forums are still overcrowded and filled with doubled information and useless posts. Let's try to keep this place as clean as we can.
Thanks

data speeds on tilt 2

i found a different thread but it talked about the icon.
i recently picked up a tilt 2.
now over wifi, with the att proxy disabled i compared my tilt 2 to my iphone 3g.
i used speedtest net. web app on the tilt 2 and on the iphone i can only use the app.
what i found interesting is on the iphone i get 5 megs down 600k up which is about right to what my dsl line is provisioned at currently.
when i run the test on my tilt2 the max i can hit is 1.5 megs down.
is this normal? software? hardware? when i goto connection settings on the tilt it shows down speed 54mbps upload at 1.... when i click my wifi connection on the tilt.
any info would be appreciated.
over 3g i get about the same speed 3g iphone vs tilt those add up. i'm not really intrested in the slow speed over 3g what is bothering me is why is this phone so slow over wifi.

one more thing i want to add, when i connect wifi, with data off
network advance, Tx rate is 54MBps Rx rate is always 1 Mbps.
no matter what rom i have on the device.

Mine does the same thing. I contacted HTC and they where no help. I'm thinking of calling HTC again and see if I get some one else that might have a clue. You would think that when you connect to Wi-Fi that you would get better than 1.5Mb/s.

same here. Tilt 2 max 1.5

same here.
Tilt 2 with default at&t rom, sim unlocked on Roger(canada) network with the good connection settings.
Max 1.5 moslty around 1 on both 3G and wifi.

bad hardware or just how it is?
i have tried a different radio flash no change. to me it seems like bad hardware or a hard cap in the phones hardware.

does anyone DO NOT observ this problem with is tilt 2?

Yea i am at about 1 mbps as well on wifi. With full reception on 3g though for some reason i can only get speeds of about .5-.7mbps what the hell. I called ATT and they said it was the device but who knows. I bought this phone because of the fact that it had HSDPA 7.2. (I spend a lot of time on the internet) and of course some of the other great features it offers but my iphone 3g out performs it :-( really aggrivating

I have the T-Mo touch pro 2 and I use my phone as a modem for my laptop and it always feels like the internet is screaming fast, how would I check to see how fast it's actually going so I can report?

well that is because when you teather your laptop it is going through a different set of towers and uses different data (or something like that) then if you are just browsing from your phone. To test the speed just teather your phone and go to speedtest.net

Slow here on ATT Tilt 2
I also seem to have the 1.5 max wifi, G3 is even slower.
Missing the kaiser (original Tilt) already

i called htc on this matter, and the guy i spoke to is getting the same results, 1.5Mbps max.
this phone is same speed wifi and 3g in terms of load, etc i find this hard to accept, my ipaq is 802.11b and it wifi connection is not throttled to 1.5Mbps like this phone.
rom's and radio make no difference to the speed and if its hard capped at 1.5Mbps how in the world can it even hit the crappy 7.2Mbps att is rolling out backwards.

those this problem only observ on the tilt 2 or tp2 from sprint or verizon also get the problem?

Yep, I have Verizon FIOS at the house, and we have the max speed, 25 down 15 up. Testing with speedtest.net on my laptop i average 19.5 down, 13.5 up.
Turn on the wifi on my tilt2, and I get 1.5 down, 1.2 up. Ouch.

I get 0.05 down and 0.32 up. I've been complaining about it for awhile now. I have spent a long time calling AT&T and visiting the store and in the end it has led to them telling me they need to send me a new phone. If I take that option, I will let everyone know if the new phone was the same.

Oh bother, same here.... Bounces at 1.5 down, .35 up. Like it's hard-coded to limit it to that speed.
Probably another way for ATT to give network priority to the sheephone.

it's really inacceptabled. I've bought the found from a second hand here in canada. I cannot change it like this. HTC must offer a solution to us. It's not only an at&t phone. It's a world phone.

Same here too.
WiFi on my laptop gets me 6-7, but Wifi on the Tilt2 maxes out around 1.5

I would have suspected that too, but when you switch to wifi, you are no longer on the AT&T 3G network. I think it has to be a hard limit on the phone. The question is, can that limit be "unlocked" somehow?

this is the question i asked htc. they are getting back to me.
i hope this is just a software issue that can be addressed with some sort of patch.
it feels like hardware since its on stock or cooked roms.

[Q] Tmobile SIM in ATT Phone, EDGE only?

So I finally called ATT and got the subsidy unlock code for my Tilt2.
I popped in a Tmobile sim and it instantly works fine in every function except the connections speed. I am getting Edge only.
My question is, Can this be improved by the addition of a more recent radio? Or am I stuck with Edge due to the hardware in the ATT version of the phone?
I haven't played with this phone for almost a year except for a week in December or so when I reflashed to FireStorm 7.4 while my Captivate had crapped out. So I am kinda out of the loop on this. I was told the Captivate can't run Tmobile 3G no matter what radio I run. But I was hoping since the Tilt2 has been out so long someone might have figure out something. I see the FM radio was worked out after we thought it was impossible.
My rom and radio for the Tilt2 are in my signature. Any hope of updating it for 3G speeds?

It's by hardware. I have both phones as well due to that scenario.

Tmobile offers 3G on 1700 MGHZ and ATT is on 850 or 1900. The ATT phone does not have 1700, so there is no hope of your device working on TMO 3G in the Americas.
Edge is all you will get, as TMO still has the quad band GSM capability.

Thanks guys. I guess the extra sim with data is not all that handy then.
It still seems odd that even by flashing a new radio it wont work. I have digital radio equipment (scanners, Ham Radio) that has huge bandwidth and I would think that modern cell phones would have the same capability. But obviously it doesnt work.
Do the international versiopns of the phone have the extended frequency range capability or is it still the same problem?

The manufacturers are too cheap to enable all the frequency bands.
Actually I suspect there is a setting hidden somewhere in the radio's NVRAM that can change the available frequencies, but nobody has found it. The chipset is the same across most of these models, and obviously the radio's antennas work across all the frequencies (since they already do for 2G). And as one obvious example, the Samsung Vibrant (which was T-Mobile only) can have its radio software-unlocked to work with other 3G frequencies.

Interesting. My other phone is a Captivate, which is pretty much the same as the Vibrant. I have been looking into a dual Sim adapter to run both my ATT and TMO sims in the same phone. I was told the Captivate cannot run on the TMO 3G frequencies. I will have to look into this further. That is very good information. Thanks.

I know where that setting is but the limitation seems to be in hardware.
either that, or there is a lot more hacking required than just changing the NV setting.

Hey, care to share? Can this setting be toggled using e.g. AT+HTC_DM? Is it a no-op or is there any visible effect from changing it?

[Q] AT&T and Radios on CM 7

First off, a real big thanks/"you the man!" etc. to Cyanogen for CM 7. Finally took the plunge and rooted my phone, warranty be damned. Let's just say I had an older Aria (which had already been rooted) as my training wheels, and it certainly was nice, but nowhere near as nice as the DZ/Vision.
So let me get my specs out of the way:
Baseband Version: 12.28e.60.140fU_26.04.02.17_M2 (I gather the bold part is what we refer to as the radio version).
Kernel Version: 2.6.32.28-cyanogenmod-g4free2e [email protected] #1
Using CM 7.0.3
Now in running Speed Test, I'm getting about, ranging from .45 Mbps, going as high as 1.60 Mbps in terms of download with upload being only slightly behind, sometimes being even. Now the results don't make sense, and I know I've gotten significantly higher in my area, and browsing does seem slower many times latesly.
So should I change my radio (again)? I had changed it (probably shouldn't have) thinking I could get more consistent mobile Internet connections, but I guess I've kind of screwed up. Any suggestions from fellow AT&T users?

I'm in the same boat, about to get my Desire Z. Not a ton of AT&T users for the Vision so I wasn't sure whether a different radio would benefit or not...

I've gotten up to 5 Mbps down on the stock radio. But obviously, this is going to be dependent on your local network (whether or not the HSPA+ backhaul has been performed, and network congestion). It would be ideal if you could compare data transfer rates with another AT&T customer in your immediate area, preferably on an Android device.
Only time I've switched radios, was when I tried Virtuous, and used the radio that is recommended for that ROM. Did not notice any change in data speed.
I assume you have the Canada Bell version of the Vision. In that case, you never had a warranty. HTC states in their terms that any phone purchased outside of the country it is intended to be sold in, is not warrantied.

I am on 12.28b.60.140eU_26.03.02.18_M3 CM7
I get 1~1.5 MB/s Down and <1 MB/s during peak hours. At 3am in the morning i get 3-4mb/s Down and 1.35 mb/s up. This is from an Suburban area too...
Once I get into the SF City CBD area during 8am hours i get 300kb down lol. And all my data no longer work.
Also I have an iphone 4. It makes no difference when i switch the sims. Same data speed.
I used to use RUU_Vision_Hutch_AUS_1.85.861.3 when i had issues with 3g dropping to edge all the time.

Really? No warranty, eh? Well I'm going to have to look at those terms again. Not like it matters now anyhow.
Sadly, most of the AT&T users I know are iPhone users; however, there are a few I know I could ask.
Yes I have the Canada Bell version of the Vision; however, I don't remember the stock version of the radio, so I'll have to do some digging unless the stock radio is what's in your sig. If that's not the stock radio, well, I can always try it.
Anybody else (particularly in New England/Northeast USA)?
Thanks again!

I should have an unlocked Bell Desire Z in my hands in the next few days. I'll do some testing and see what results I get.

Thanks! Keep us posted, cause I'm sure there are several of us here on AT&T. I plan on testing next week.

Kk, so finally got the phone unlocked/working. I ran a few tests from a few different places and got the best result to be 2.4Mbps down and 1.1Mbps up. I'm not really sure if those are hspa+ speeds or not and don't have my friend's atrix here to compare at the moment. I'm also no sure but he was telling me that if I want hspa+ speeds at&t needs to activate something for me. Can anyone confirm? Or at least tell me a way to be sure of what I'm currently on?

Stock radio is: 12.28b.60.140eU_26.03.02.18_M3
Where in New England? I'm in the Boston area. Data speeds vary greatly depending on exact location. I get good speeds at work (Burlington, MA), often 3-5 Mbps down (but sometimes dipping to 1-2 Mbps). While at my house in Waltham, its abyssmal, with speeds often around 0.5 Mbps down, or even less. Luckily, I'm always on WiFi at home.

I think it always says 'H'. Just tested at 4.11 Mbps down, and it says 'H'.

I'm in California, in the greater Sacramento area. I have a Desire Z NAM that I've been using on ATT since about last November.
I don't believe the backhaul overhauls have been done in our area yet as I haven't seen an increase in data speeds lately.
During the day, I average downloads of 1.5-2.5mbps and uploads of 1-1.5mbps. Of course during off peak hours, those numbers go up a little bit but not drastic. When heading into the bay area, specifically into San Francisco they tank hard, to the point where I'm better off switching to EDGE...
I am still running CM 6.1 with radio 12.28b.60.140eU_26.03.02.26_M
My GF has a Dell Streak on ATT and she gets comparable speeds to my DZ. Haven't tested it for exact numbers but I don't feel a significant difference when using her browser against mine.
Haven't done any tinkering with Radios either, perhaps a project for summer when I get some vacation time...

Haven't had much time to test as the company move has me working massive amounts of overtime (hey, at least the paycheck is huge).
I live in Connecticut; right outside the Greater Hartford area. I plan on moving back to the stock radio to see if anything gets better, so we'll see.
Granted I plan on being in NYC this weekend, so testing may not happen seeing as how AT&T's service is like rhino poop in the area.
(Yes, rhino poop).

I'm on stock radio and I have zero service in my basement. Service was never that great down here, but I always got one to two bars. Can anyone point me to radios to work specifically for AT&T Desire Z users or does it make a difference if we use those other ones (like T-mobile)? I've seen the thread with all the radios, but I am clueless as to which ones I should try.

[Q] Hardware, roms, and 3G frequencies...

Hi - I'm looking for some good answers - I think I know the basics...
After much shopping, I bought 2 of these...
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=170623785892&ssPageName=STRK:MEWAX:IT
(HTC Touch Pro 2 s - the wife likes for our phones to match so I can teach, set up, etc...)
I think they are called T7373 SEA's South East Asia Versions, and I flashed to 2.07.707/4.49.25.91 radio just fine to get current at WM6.5. (I like factory ROM's - the books work, etc - despite my appreciation for the effort to cook.)
Now - I'm currently ATT, and when they go to Data Plan me, I'm going to T-Mobile prepaid.
So - I get to looking at 3g frequencies - of course!
The book for the device says 900/2100 HSPA/WCDMA.
The sellers' ad says
3G Network HSDPA 900 / 2100
HSDPA 850 / 1900 / 2100 or HSDPA 1700 / 2100
(It's not really clear what the 'or' means)
Now, I'm not *****ing at the seller, I want to really understand, and they knew I was US and they asked ATT or Tmobile.
Would they like have reached into one of three bins, to sell me one of three truly different hardware phones - OR - picked a phone up and flashed it (Radio or full ROM) to my provider, or did they just configure the existing system so it picked Tmobile and its freqs for instance? (When the phone boots, it asks T-Mobile or 2 other Asian-sounding systems) How else could the phones do as advertised? (9/21, 8.5/19, or 17/21)
If the frequencies are not a settings, but a ROM/Radio issue, can I load the 'other US guys' flash and have it work?
If not, does anyone know what really is changed in the hardwares (I imagine the antennas' length might vary by X%, but then here that's % of mms.)
Thanks - great answers and experience really appreciated!!

The device in the picture of the ad is a European unbranded model (RHOD100). It's 3G frequencies are on the 2100MHz band. If they sent you the one pictures, you will not get 3G with any US provider. AT&T uses 850MHz and 1900MHz for their 3G service, while T-Mobile uses 1700/2100MHz. 3G radios are hardware dependent, not software dependent. This means that you must purchase the device that contains the radio for the 3G service you wish to use. They will work on 2G networks anywhere in the world. 3G is really the only difference between carriers.
The AT&T device is the RHOD300 model, also known as the Tilt 2. The T-Mobile version is the RHOD210.
The short answer is that if they send you the exact device in the picture from the ad, you will only be able to get 3G in some parts of Asia and Europe.

The description on the eBay listing is just cut and paste from somewhere (like HTC's website), so that is why it says "or" for the 3G bands. One is for the Euro model, the other is for the Asia model. Either way, neither have the correct bands to give you 3G on AT&T or T-Mobile. And as cajun mentioned, bands are hardware dependent, and there is no way to change it.
If you want 3G on AT&T, you need to buy the AT&T branded Tilt2. But since they will be able to read the IMEI number of the phone (since its ATT branded), they will probably add a smartphone data plan very quickly. So its probably not even worth getting a Tilt2, if you don't want a smartphone data plan. If you want 3G on T-Mobile, you need to buy a T-Mobile branded TP2.
Bottom line, if the phones you bought are unbranded, then they don't have the correct hardware to get 3G on either AT&T or T-Mob.

Hey guys(?) thanks, I think I understand.
So - basically the ad HAS to be a lie, at least for 3G.
So I'm still wondering... What does HTC actually change in the phones - a crystal (I doubt this in modern times), a chip, a pack, an antenna length? There is a small area in the phone that looks 'potted' we used to call it.
They are way too pretty, and way too functional 'as is' to mess with (so I'm not gonna go module or whatever shopping), and we are pretty much 'emergency only' web people (for maps, pizza places, etc) and 2G will be fast enough. The value of a keyboard for texting, the Windows interoperability, and no damn contract is good enough.
We are deciding which ROM level we want before we try ATT to see if they know the numbers... T-Mobile prepaid is the backup plan.

A lie in that it looks like a lazy cut and paste, with either no proof-reading to catch the error, or a seller that does not fully understand what he is selling. They are a high volume seller, and also just used stock photos (not photos of the actual item), so its just a rushed auction posting. I don't think it was an intentional lie meant to mislead you. But if you want to dispute the sale, I think you have very good grounds, since the information in the auction is incorrect, and its actually impossible to tell what exact model (Euro or Asian) they are selling from the description.
AT&T most likely won't be able to correlate the IMEI with the right phone brand/model. But I've seen cases where they think its a smartphone, but the wrong one, and try to add a smartphone plan. I read a post where a guy was using a Nexus One, and their system was reading it as a Blackberry. I think he just told them it was an unlocked dumbphone, and they removed the smartphone plan.

Please Correct me if I'm wrong...
presently I'm using Sprint Touch Pro 2, and I have read on the internet that it is possible to work with AT&T or T-Mobile (which uses different technology other than Sprint's CDMA) after proper unlocking. Is it possible?
Regards.

Yes, but you will not be able to use any other network's 3G service. The best you will get is EDGE on another network.

To follow up...
ATT stuck me on $25 Smartphone within 24 hours. (We went to $15 later, and they dropped us to a $10 cheaper talk plan.) For this particular set of phones, apparently the first 8 or so digits of the IMEI is phone type (which they clearly knew from Tilt 2's) and the rest is item serial number. Couldn't argue there...
Speeds, freqs... I don't get a clear definition of G's anywhere, but I show a H before I long on, and another H with bars as I use data. I have used cellular data at up to 1.1mbs per speed sites - I don't know if that's over E, or G, or H but it seems pretty fast to me. All that's on ATT, when I went to the T-Mobile store and tried their card, the best I got was 200kbs on about 5 tries.
Love the phones, added HTC task manager pulldown, and 1.6 VC from here - THX

G stands for GPRS, and it is a 2G service. It stands for General Packet Radio Service. It is the slowest data service you can get with speeds normally under 50Kbps. It is occasionally known as 2.5G service.
E stands for EDGE. It stands for Enhanced Data Rates for GSM Evolution. It was a revision to the 2G service implementation and features speeds from about 100Kbps to 250Kbps depending on location, service provider, and signal. It is occasionally referred to as a pre-3G technology. It fits in the ITU's definition of 3G, but few people refer to it as such. It is normally marketed as 2.9G.
UMTS (Universal Mobile Telecommunications System) was a revision to the voice service, and did not address much data-wise. This was the first widespread usage of the term and use of 3G. It is normally the service that your device is using when it shows the 3G icon. 3G speeds are normally 350Kbps - 500Kbps.
H stands for HSPA. It stands for High Speed Packet Access. It is one step higher than what is commonly known as 3G.It is also known as 3.5G. It features speeds closer to 1.5Mbps. HSPA is normally grouped in with 3G service when it is being discussed.
As for your test with T-Mobile, that wasn't really a fair comparison since you can't get 3G speeds on a Tilt2 on T-Mobile's network. You can only ever get EDGE service. Therefore, you were comparing AT&T's 3G service to T-Mobile's EDGE service. This is like trying to race a Mustang with a Moped. If you get the Rhod210 model, you will get the faster connection with T-Mobile. There isn't much to compare between AT&T and T-Mobile. AT&T 3G speeds are slower than T-Mobile. The services are also much cheaper on T-Mobile.

THX for reply, I generally understood all the abbreviations, but like you said - the marketing hype really seems to very from the technology.
If I saw, regularly, over 1 mbs and the H bars to the right of the H block, do ya' think I was H/HSPA over 8.5/9/19/21 freqs?

On AT&T it would be HSPA on the 850MHz and/or 1900MHz frequencies. T-Mobile uses 1700MHz for HSDPA and 2100MHz for HSUPA. The frequencies for 2G services are all the same for everyone. This is why you will get up to EDGE service with any GSM carrier, but never 3G service unless you buy a device that explicitly supports that carrier's 3G service.
