Hi I updated my iPhone 4 to iOS 5 today (a little late I know) & when I send an iMessage to my sister or boyfriend my email address comes up on their phone. As if I have emailed them, but when they reply to me their normal name comes up on my phone. I have been into settings and chosen caller ID and ticked my phone number instead of email address. I have reset my settings & restored my phone but still they are receiving from my email address not my number ??? Help please.
