This is my first post on MacRumours but ive been visiting the site for many months now. I thought id inform you of some info that i recieved from the O2 Website as regards to MMS Registration. You have to have the latest software on the Iphone, So 3.0 Beta 5 To recieve and send messages all you have to do is send "ACTIVATE" to 1010 Then you will recieve a message saying we are setting up your MMS and then about a minute later you will recieve a picture message from O2 saying it has all been set up. Just to let you all know, if you get stuck, give me a shout. Cheers Dan.
