upgraded to ios4 GM but now no visual voicemail setting or mms... o2 UK

as title says really.

There is no input boxes for visual voicemail settings and when i enter the correct details for mms i still cant sent or receive them

any ideas?

Thats exactly how i did it, maybe some settings didnt make it across or something, i guess ill wait for monday for the official release and see if that fixes it, just ghey i cant use mms even tho all settings are correct etc
