Hi everyone 
So I have a used 4S (iOS 7) from a friend (who's upgraded to a 6).
It's 'de-registered' with his Apple account. It was originally bought from an Apple Store on a Vodaphone contract.
Can I buy a sim from another network - say O2, giffgaff, 3, etc - and have the phone work ok? I'm reading that it may by 'locked'?
Currently the phone is in it's 'Hello....' state ready to be registered - it won't let me register it without having a sim.
Any advice is welcomed
