IOS 6.1 IMessage sends texts as emails?

Yesterday, I updated my iPhone to iOS 6.1 and today, I noticed that it was sending my iMessages from my email address. I tried to change the "Send/Receive" settings, but it only allows me to use my email. I've checked everywhere in settings, and it i couldn't find anything. Is this permanent with iOS 61. Or can I change it?

I believe you always use your email address because that's your apple ID that you use to send the messages in the first place

Xx if you have no idea what you are talking about, then don't answer… Clearly you have no idea.

I'm having a similar problem. I can only send/receive imessage via my mobile number and not my email. Trying to send a message to an email simply reverts to MMS via the carrier. They clearly broke something AGAIN. Look for a 6.1.1 update to address this issue.
