Answer 1

As long as they frequencies match yes. Just drop your new AT&T sim card into the phone and go !  

Answer 2

as long as its either triband or quadband, it sure will work... i have n82 and n73 from the philippines and using it here in california with at&t...

Answer 3

The cell phone MUST work on the 850 and 1900 mHz bands to work on networks in the U.S.  If the phone works on these bands, is unlocked, and uses SIM cards, then you should be able to use it.
