42Mbps T-Mobile Amaze supports AT&T HSPA+ frequency?

[colnago]

It looks like the T-Mobile HTC Amaze supports UMTS on AT&T's 850 band. I currently have my T-Mobile Defy running on AT&T's 3G via the less expensive ($15/mo.) Unlimited "Media Net" plan. Time to upgrade?

• Band (frequency): 850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (1700/2100);UMTS: Band V (850)

you do realize 42meg is theoretical and not actual speeds. but yes, any phone that works on AT&T will work on T-Mobile, its the exact same technology, same frequencies.

My point was that the Amaze is one of the first "42Mbps capable" phones to be released, for either carrier, and one would be able to enjoy "faster speeds" at possibly a lower monthly rate (depending on one's plan). Again, being that its a non-AT&T branded phone, it would not be considered a "smartphone", and subject to the mandatory plan. A viable option as many complain about the poor selection of good Android phones on AT&T. However I used a "?" in the title because info on a carrier's product pge is not always correct...as in the case w/my current Sensation 4G. 850 UMTS support was listed on the T-Mo site, but removed around the time of its relase.

As far as AT&T and T-Mobile utilizing the same HSPA/UMTS frequencies, as carriers, that is incorrect. T-Mobile uses 1700/2100, while AT&T uses 850/1900. Most carrier branded phones will "work" on the other carrier, but only at Edge speeds. The Amaze, much like my Defy and a few other rare exceptions, are examples of 3G capable devices, which function at 3G speeds, on "both" carriers.

What about going the other direction?
Does ATT sell any Android phones that will work cross carrier like that?
In other words, are any ATT phones capable of using the TMO frequencies at the higher 3G speeds?
I am ready to upgrade from My Captivate but would dearly love to have a phone I could use with both carriers at 3G speeds for data once its unlocked.

"From AT&T", doubtful...unlocked version from manufacturer, there may be a few.

So the Defy and the Amaze both from Tmobile work on the ATT side with 3G speeds though?
Interesting. It might be time to finagle something with a friend.
Any other Tmobile phones with Android that will do that?
I have both ATT and Tmobile sims with data is why I ask.

On paper, the Amaze supports AT&T 850, but I have not read about any confirmations. Otherwise, I believe there is a Samsung Galaxy of some iteration which works on both carriers' UMTS.

This may have a lot to do with the proposed merger....that looks like is tanking.

ATT 3g bands listed on the box? - xda-developers

This thread on xda says the new Amaze 4G from TMO works on ATT 3G.
