The network options are set by the carrier file installed on the phone.
Check to make sure you have the latest, but I wouldn't be surprised if O2 have removed the 3g only option.
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
