When my phone is locked, sitting on a desk, it will suddenly call someone. It could be anyone from my list, so not the last number dialed or something like that. When I disconnect the call, it immediately returns to lock. It is not them calling me, I am definitely ringing them. Since 2.2, I've had a lot of other issues. My two email accounts were mixing up emails (I was sending out my bank balance to customers!). Hard reboot fixed that. I can't open my outlook inbox. I would like to remove 2.2 and keep with 2.1.
