When iOS 5 first came out, I added my @me address to my iPhone and iPad. People could iMessage me at my email address, and I'd see it on both devices. This wasn't always perfect, and recently I decided to forgo this, and just use my phone number on my phone and email address on the iPad.
So, I switched the caller ID on my phone to the phone number again, deleted all my text message threads that were created when I was using the email address, and started a new thread. Somebody who didn't have my email address saved in their contact asked why my text messages were coming from an email address, and another reception confirmed that when he tapped 'Contact Info' at the top of the message thread, my email address was highlight in blue, NOT my phone number - indicated that this is where the message was coming from.
Does anybody know why this is happening? Is there another setting I need to change? I'd really prefer to not have them come from my email address, because then any replies will goto both my phone and my iPad - which I don't want.
