Here are the settings for PAYANDGO O2 UK
I have successfully used these on a milestone with working full size MMS, this is the result of about a years worth of switching handsets & trying
every list of settings listed on the net....

Here are a few tips if you have problems with MMS
1: If you have a T-mobile sim, insert this & send a picture message, then switch back to your O2 sim.
2: If you have an iphone sim insert this then request settings by sending the word "mms" to 1010 - you will get an error saying only available on iphone, insert your regular sim back.
The MMS issues are not with Android, they happen because there is a white list of supported handsets at O2. if youe phone is not one of they sell/support they will resize your pictures to a tiny thumbnail size.
There is a APN mms app that tricks O2 servers into thinking your phone is a Nokia or Iphone, I will did it out & upload soon.....
