So, we all know that there's no official support for T-Mobile's network if you buy an iPhone of any variety. However. Will the iPhone 4S on T-Mobile's network be 3G compatible finally? I read somewhere that the cellular chipset in the 4S supports the AWS bands that make up the 3G network, but they might not be enabled. An older snapshot of the (then prototype) iPhone 4S (N94) shows it as working on T-Mobile's 3G network. I am switching from a iPhone 3GS with GoPhone service to T-Mobile, and I'd like to wait to see if it supports 3G via jailbreaking. Although if they aren't unlocked, I'll get the 64GB 4S with AT&T, then pay the ETF fee after a month, then jailbreak/unlock and use with T-Mobile.
