I would like to switch mobile carriers. To do that I need to unlock my iPhone for GSM service then install a new SIM. how do I know whether it is locked or not and if it is, how do unlock the iPhone?
Thanx

Q: how do I unlock my iphone to switch carriers?
You contact the carrier it's locked to and find out what their requirements for unlocking the phone are.
ONLY the carrier the phone is locked to can authorize unlocking it.
