Many thanks Ed

Restore the device, then take it to the phone provider to be unlocked.

I just phoned vodaphone and they sorted it out with apple. Might take a couple of days to come through and unlock.

Thanks I’ll ring my brother later and ask him to do this for her.Will this jailbreak thing she has had done be a problem?

Probably not; may need to put the iPhone into DFU mode (Google exact instructions, but it’s just a sequence of pressing power & Home button) prior to connecting to iTunes on a Mac or PC to get the unlock to take effect.
