Can't restore My iPhone 4 from iPhone 3GS backup?

Today my girlfriend got an iPhone 4 after her 3GS broke. She brought it home and went to register/set it up. We go to do the restore from back up and nothing happens. We wait for 15+ minutes for it to happen and all it does is make us do it all over again.

Can I unlock my iphone without jail breaking it?

I bought a brand new iphone 4s which was advertised in our local paper. It was a brand new upgrade that the person didn't want. Inserted my three SIM card into it and its locked on 3. However, the mobile phone transmitter has been down in our area for the past 23 days due to technical problems and I've been left without a phone signal. Three can't give a date when it will be restored. I've tried to leave 3 and go to orange but 3 won't unlock the phone because they said its registered to someone else. I bought it in April and don't know the guys name or date of birth. Does anyone know a way round this? I've spoken to apple store and they said three are just being very awkward, its very frustrating as i don't have any network coverage on 3 and now can't change to orange as the SIM won't work!
