Quote from Seldoon182- Where to shop a prepaid phone card ? How much its cost ? Will the SIM compatible with my iPhone 3Gs ? Is Minos gay ?
More than to worry about the SIM, I think you should verify if the phone can operate in CDMA networks, i remember iPhone were sold separately for US market and rest of the world (GSM) until iPhone 4. But maybe "rest of the world" phones can double operate(?).
