Help With Swirly MMS on O2

[Chr1s_888]

Hi there,

I have activated MMS with O2 on iPhone contract. It has been working on a K800 Sony Ericsson sending and receiving. It was working on my iPhone for the past 3 days but now it is not working as the green "M' has disappeared. i have not changed any settings apart from rebooting phone which has now seem to have screwed up Swirly MMS. Just wondering if anyone else on O2 with Swirly have had any problems like this. Any help would be much appreciated! Cheers!
