Do i need to unlock?

[skiptowncat]

I currently have an 8gb 3g on 02 network, and was looking to buy a 3gs. If i buy a locked uk 3gs will my 02 sim card fit straight in and work?

Yes it will work with no problems,If your 3G is on contract or over 12 months old on PAYG get it unlocked by O2 (free for contract or £15 for PAYG)so you can use any simcard with it.Unlock my iPhone - iPhone
