When you unlock your iPhone for global roaming on Verizon, is it tied to the phone number? Does anyone know what happens when that phone is deactivated? I was thinking of selling my phone and unlocking it for international use. If I call Verizon to unlock the phone and then sell it to someone, and they never reactivate it (they only use it internationally) would it have relocked? I'm sorry if this is a bit confusing. Thanks!
