Hey, After upgrading my iPhone 5 to ios7 on Wednesday if appears I am having a few issues with iMessage. 1) My phone number is greyed out in the 'you can be reached by imessage at' part of settings meaning people can only imessage me if they have my e-mail address added in their phone directory. 2) People say they can't iMessage me, only text - odd. Ideally I want to send and recieve iMessages ONLY from my mobile number (my apple e-mail address is pretty juvenile - I don't want to be associated with it if possible I've tried a number of fixes such as resetting all settings on my phone, signing in/ out of iMessage etc.. any ideas of what the issue might be? Could it potentially be something to do with iCloud? I never bothered setting it up until ios7 came out. Cheers for any help!
