The iPhone 5 that will be sold through T-Mobile is a modified version of the A1428 iPhone 5 that is currently produced for AT&T's network, among others. The new version of the A1428 has been tweaked on the hardware side by Apple to support Advanced Wireless Services (AWS) bands for T-Mobile's network.
According to an Apple representative that spoke to Engadget, existing A1428 phones cannot be updated to add AWS support.
Apple’s enabling support of the AWS bands from the factory on the new guy – and sadly, Apple affirmed to us that it's not something that can be enabled via a simple software update for A1428 iPhone units already in circulation. To say that another way, existing iPhone 5 owners on AT&T cannot simply apply a software patch to have AWS support added. You'll need to buy a new phone next month.
On April 12, which is the date that T-Mobile's iPhone 5 launches, Apple will be selling the new version of the A1428 iPhone. This phone will be available unlocked at full retail price through Apple, and will function with both the T-Mobile and AT&T networks, as well as on many LTE bands around the world.
Apple plans to phase out the existing A1428 hardware in favor of the new version, which means future phones from AT&T might also ship with AWS support included. While the current A1428 phone works with T-Mobile's network, it is notably slower than the modified version.
Apple's iPhone 5 with AWS included will be available at 12:01 a.m. on April 12 from 24-hour locations, and phones ordered from Apple's Online Store can be unlocked (after full payment) through T-Mobile.

Then why did you post in the thread?
I would say that you should care, because it means that not only is this version of the iPhone 5 now to be more sought after, you could now take it to another non-CDMA carrier without suffering any degradation of service due to the same bands being supported.
BL.
This is the first thing to piss you off in 20 years?? Adding another wireless frequency to the iPhone? lol
Existing A1428 on T-Mobile
--------------------------
- Will be 3G in refarmed (1900Mhz support) areas
- Will be EDGE in non-refarmed areas
- Will work on LTE once deployed (Band 4 LTE supported)
New A1428 on T-Mobile
-----------------------
- Will be 3G in all areas (due to AWS 1700 Mhz 3G/4G support added)
- Will work on LTE once deployed
So, it looks like the existing unlocked iPhone 5 users on T-Mobile won't have to buy new hardware to get LTE. The only difference is they will be stuck with EDGE in non-farmed areas, whereas the new iPhone 5 owners will get 3G everywhere.
It also seems they are adding more bands LTE bands though? Wondering if they are adding 1 (2100 MHz), 3 (1800 MHz) and 5 (850 MHz)? Essentially combining Model A1429 and Model A1428?
