Alright, Yes I am on AT&T, my MMS has been working flawlessly since it first came out a while ago, but today I decided to update my iPhone 3G to 4.0 and now MMS no longer works! The camera button next to the text-field in SMS is not even there anymore. When I go to photos and select a photo I no longer have the option to send in a message. And I can't even copy a picture and paste it into the text-field! And when I go to settings>Messages the "Enable MMS" button is no longer there! it just has "Show Preview", "Repeat Alert", and "Character Count". I have tried restoring and it still did not work! Has this happened to anyone else? Does anyone know a solution? Or I'm doomed to wait till Apple releases an update?
iOS4 is basically a nightmare for lots of people who don't have an iPhone 4g. You also can't revert to 3.1.3, so you just have to wait.
