I am in NYC and bought an Iphone 4G with part#MC318LL/A from an electronics store on 34rth Str. The store manager said it can be used outside US on any GSM carrier ; however it says on the box at&t and in settings :Carrier :ATT . I suspect that this is probably a locked phone .
Question: How to tell it is a locked phone or Not before I travel overseas?

Toshiba, Windows 7, i5
