I installed the 3.0 beta and am only having one major problem - I cannot type in the body field of any email from the Mail app. I can type in the subject field, etc., but when I tap on the body to compose the body of the email, there is no blinking cursor and, although the keyboard remains and takes presses, there are no letters. In addition, when I hit send, the message composition screen goes away, but nothing is ever sent. The strange thing is that mail composition sheets from other apps (like Photos) work and send mail fine. Any ideas? I have Gmail and Mobile Me accounts both set up. Would love some help if anyone has seen and / or solved this. Also, this problem occured when I did a update from backup AND when I set the iPhone up as a new device.
