6230i - Unlock code please? help!

I have a Nokia 6230i:

Vodafone (UK).
Serial No. 353268013780446.

Would anyone be able to help me unlock it as I would like to use it on the O2 network.

Thank you

1. Insert a non accepted sim, most times it will show "Phone Restricted"
2. Press the UNDO option
3. You should see a box that says enter restriction code.
4. Enter the code given and then press (OK)

 

just wanted to say thank you very much.

 

Thanks for the response and glad to see it worked for you.
