6110 Navigator Unlocking

[jonchill]

I've just bought myself a second hand 6110 and want to unlock it so I can use my sim card, currently on Vodafone SIM for O2.

I've put in all the details it asks for on the unlock page and entered the code but it comes up with a message saying not allowed.

Why has this happened and how to do I unlock the phone successfully?

Thanks

Jon
