I'm currently experencing a problem where 2.2 will refuse my PIN when I try to unlock the phone, no matter how carefully or precsiely I enter it. It's an intermitten issue. Sometimes the PIN works sometimes it doesn't. It feels like its getting worse too. This morning I had to enter my 12 times (2 lock outs) before it finally took it. I've tried reseting the PIN. Same issue. I'm also experencing another issue which may be related. Sometimes I unlock the phone and arrive at the home screen only to watch the phone scroll all the way to the left most home screen. When I try and swype it, it moves the page until I lift my finger and immedatly slides all the way back to the left. Any ideas?
