Hey all, my Telecom iPhone 4 (stock standard model) has just decided to stop sending MMS, but it continues to recieve MMS happily. I've done all the usual things such as powering off, upgrading the iOS (to 5.1.1), reset the Network Settings and tried sending a totally new MMS (not resending an old one) - but no luck. It's showing 2.4Gb spare memory as well.
Ideas anyone?
Many thanks
