Hi all, got my iphone 5 on Sunday on o2 and not been able to send MMS at all. I tried sending one to myself and it worked but tried to send a pic to others and it just comes back with the little red exclamation mark. I went on o2 to try and solve it and it told me to send a text to 1010 an all i got back was 'Sorry this is currently only available to iPhone users.' Erm. thanks for that! any clues on how I can get it to work? Just wondering if it's a phone issue before I ring and bash o2!
