I currently have the samsung flight 2 for at&t and my friend just gave me her iphone4 for at&t.can i put my sim card from the flight 2 into the iphone and it will continue working fine, or what? if i cant, will it cost me to go to the at&t store and get a sim card and switch my number over? thanks.
