Yeah, so I am completely in l?ve with the T-Mobile Aria. The AT&T version is MUCH smaller than the T-Mobile one.
I know T-Mobile and AT&T both take sim cards, so there shouldn't be any trouble, am I right?
Pl0x help me...
Links are l?ved very much. To both is necessary...

Thanks Y.A.C.

Also, where can I buy the T-Mobile one coz I keep getting AT&T's version when I search it. >
