1. Make sure that you are on 3.0 GM
2. Go to Settings / General / Reset / Reset Network Settings
3. When rebooted, check Settings / General / Network / Cellular Data
It should now have an APN of idata.o2.co.uk for each of data, MMS, and Visual Voicemail
4. Send a text message containing the word "MMS" to 1010
5. You will soon receive a picture message from O2 telling you it is all working
Good luck guys!
