A few days ago i restored through iTunes using a back up and ever since iMessage will only work with my email and not my number as it says it can't verify it. i have tried numerous clean installs and trying to install the previous backup again even wiped it through the remote wipe in iCloud (don't ask me why i thought to try this but nothing else was working so i thought i may as well try) but nothing works. I have even been on the phone to apple for over two hours today and they didn't have a clue. Does anyone have any idea what i could do to fix this? its an iPhone 4s on the latest firmware.
