Switching from O2 to vodafone with an O2 Nokia 6230

Hi All,

I've switched from O2 to Vodafone using a Nokia 6230 which was
'locked' to o2.

The phone has been unlocked but the operator menu is missing so the
bottom right menu button reads 'O2' even though I'm now using the
phone on vodafone.

Does anyone know how to get the operator menu back so I can configure
the phone for vodafone live etc?
I also need the correct setting for vodafone live and GPRS so I can
get it working properly. Does anyone have these also?

I have already been to the vodafone website and configured my fone for
live, but nothings seems to work still, even though the default
connection seetings are set for vodefone.

Help me please!!!!
