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.
