Hardware for iPhone locked into AT&T

[downsouth00311]

So the tech specs for the iPhone 4 are as follows...

UMTS/HSDPA/HSUPA (850, 900, 1900, 2100 MHz)
GSM/EDGE (850, 900, 1800, 1900 MHz)

T-Mobile runs on UMTS1700 for their 3G network in the US. So... needless to say... it looks as though the iPhone 4 is only wired to work with AT&T on 3G.

Anyone have the current specs on Verizon or Sprint? I don't believe their 3G networks are still compatible with these radio frequencies either.

Verizon and Sprints 3G network is CDMA based, not compatible at all.

this illustrates the fact that the iPhone is EXCLUSIVE to AT&T in the US
