If I unlock this beast, can I run it on tmobile bands + 3g or no?
No, it only has bands 850 and 1900

I want a 3g enabled smartphone/PDA for t-mobile, not the G1 dont like it. T-mobile 3G uses bands 1700 Mhz and 2100 Mhz right? So if i buy a phone that supports HSDPA 2100 Mhz will it work on the t-mobile 3G data network?
t-mobile is a gsm network though, so i don't know that an hsdpa phone would work with them (first of all no sim slot)
tmobile's 3g is new and not fully released so it would be difficult to find a phone that supports their 3g (you won't find anything but the g1, and you couldn't unlock a phone from att to support there 3g because the bands are different)
This is my understanding, but if i am wrong you guys can correct me
as stated here, then does that mean that a SIM-unlocked CDMA Touch Pro2 could use at&t 3G being that it supports GSM 850/900/1800/1900?
Also, what are the differnt GSM frequencies, and how are they differentiated (GSM, UMTS, HSDPA, etc.)? (ex: at&t 3G - 850MHz)
I thought the Sprint TP2 only handled GSM on the Euro bands, unlocked? Basically the GSM portion is unlocked already but only on the Euro bands.
Why not just wait for the AT&T version?

Okay, so the Verizon announcement document for the Touch Pro2 states "GSM/GPRS/EDGE 850/900/1800/1900 MHz WCDMA/HSPA 2100 MHz". And, I'd imagine the Sprint version to use the same.

As a CDMA user, I'm not familiar with the various frequencies on GSM networks. Can someone provide some clarity of the following bands?...
US T-Mobile 2G/3G...
US at&t 2G/3G...
Europe/Asia 2G/3G...
i remember reading somewhere on this forum that the radio is software AND hardware locked so you can't use GSM in the US, only for international.
at&t 2g: 850/1900 Mhz depending on region (i think...)
at&t 3g: 850/1900 Mhz
tmobile 2g: 1900 Mhz
tmobile 3g: 1700/2100 Mhz (only 1700 is currently implemented, HSDPA+ will use both)

I'm grateful for, thanks.
...Which could mean that at&t's 850MHz band oughta provide 3G, given the Touch Pro2 is SIM-unlocked/able to access US GSM networks, right?

if what i heard is correct, then you cant because SIM lock is software. On top of that, there is hardware lock. So even if you unlock the SIM, there's the hardware lock to bypass, which isn't easy/impossible.
here's another thread about it

I work for Tmous retail sales and we have never really been taught anything about bands. Ive been pretty curious myself since some customers come into the store with AT&t phones asking about tmo service. I have been instructed (by a fellow retail associate) to tell them that no At&t phone will ever have 3G on tmo ( I assume thats just the safe answer though).
real question!
in terms of 3G/4G (hspa+) what bands does tmous use?
same question for AT&t.
To tie that together. ex: If a phone from At&t hypothetically has capabilities to use the same bands as tmous and is unlocked, can it get 3G/4G service on tmous?
i did search around and didnt find a very clear answer so i figured i'd start a thread, im sure other noobs have the same question.
T-Mobile uses 1700 2100 MHz bands for 3G/"4G"
AT&T uses 850 and 1900 MHz bands for 3G/"4G"
Yes if a phone has all those bands for 3G, and it's SIM unlocked you can get 3G on other cell company.
The T-Mobile Vibrant actually has those AT&T bands too, if you SIM unlock the Vibrant, you can get 3G on AT&T.

It's very rare to see a phone that supports both T-Mobile and AT&T 3G bands.

Thanks for the clarification. In hopes that im not being a further nuisance, I was wondering, what about a phone that has 1 of the matching bands?
T-Mobile USA is using the 1700/2100 Mhz bands for 3G (UMTS)
T-Mobile Germany uses 1900/2100 Mhz for 3G (UMTS)
If you couldnt tell, im considering buying an iPhone (to develop on for fun). Will a phone that uses 2100 Mhz only be usable on USA towers (for 3G service)?

No it will not get 3G
So yesterday I flashed this phone to ICS, its great, thanks guys!
However, I have a question about radio (I'm a software guy not a hardware guy).
Apparently, this phone supports Triple band UMTS 1700 1900 2100 MHz.
Rogers Wireless in Canada 'operates on the frequencies of 850/1900 MHz'
So, why can't I connect to Rogers Wireless with 3G speeds on the 1900mhz band? Does the phone require both 850 and 1900 MHz UMTS to operate 3G on a 850/1900MHz network?
The best connection I can get is EDGE and it's painfully slow...I bought this phone before I had a data plan with Rogers, so I never quite realized this issue...I guess I could just switch to WIND I just want to understand why it cant operate 3G over the 1900MHz band
3g needs 2 bands, one for upload and one for download. And that's why most phones, for example, bringing to the T-mo network you won't get 3g/ 4g speeds since it would need both the 1700/2100 bands and not a whole lot of non T-mo phones have these bands. So in your case a phone to run on Rogers with 3g would need both the 850 and 1900 bands.
the hardware should be able to operate at those frequencies but its software locked to 1700/2100 or 2100 mhz, so if you want 3g/hspa you must be on an operator which uses one of those 2 frequencies

how do i software unlock it? Does cid uunlocking do this?
Although I haven't use it, I often see 4G Rogers data connection when I'm in Wind's "away" zone. Assuming there are no other models of MT4GS (with different radios) I'm rather sure this phone can use Rogers 3G network.
hi i read here in a post that mytouch 4 slide is a 3g in 1900 1700 2100, but according to gsmarena it comes only with 3g 1700 2100, as some tmobile units, my questions are:
does anybody knows the real configuration (only 1700 and 2100, or not)?
is there any radio that comes with 3g 1900mhz, even if its not from mytouch 4g slide, maybe other cause i think that the hardware will work in 1900 as 3g instead of only edge like in 850mhz?
is there any secret code to activate 3g band options?
thank you very much indeed
I would trust the gsm arena spec sheet, but haven't confirmed the bands myself. And not you cannot just add bands, they are interdependent of the radio in that sense, you can not add or remove them

To make it easier instead of using the Freqs (Because they overlap with other bands) here are the Bands that the mT4GS uses: Band 1 and Band 4.
Your confusion comes from T-Mobile refarming the 1900 MHz for 3G. This is the one at&t also uses. It is Band 2.
The mT4GS will not work on Band 2 in 3G only 2G. The hardware was made for Bands 1 and 4.
Use this chart it should clear up the confusion:
