Hi ive been after an iphone for a while, and have decided to go and get one next week, I live over in Ukraine for 6 months of the year so would need to unlock the phone from O2, so i can use a ukraine sim....can this be done and how??

Many thanks.

Yes it can! I work for The Carphone Warehouse and people ask me this all the time.
You need to take it to one of them back street mobile phone shops and ask them to unlock it for you, it will only cost about £10.

Good luck with that!
