I have just bought a 910i and its unlocked and I have a o2 payandgo sim in it. The problem is that the mms setting are greyed out and set to vodaphone the is the only part that I cannot alter.

Has anyone any idea how I can set this so I can delete it or even add the o2 mms settings.

I have download the setups from o2 and all loaded ok until it got to the mms setting and then it said "sorry cannot alter this as it is a read only" SO HOW DO I CHANGE IT.
