Unlocking is the removal of SIM restrictions on the modem, allowing the use of the iPhone on any carrier. There are 2 types of iPhone unlocks:
• software unlock: the iPhone is unlocked by a software
• hardware unlock: modification have to be made to the actual hardware to unlock the iPhone
The main reason to unlock your iPhone is if you want to use it with a different service provider (ie T-Mobile).
