Sony Ericsson Xperia X10 :: X10 Sending Text Messages Randomly, By Itself

I have been having a problem recently with my phone sending text messages to random nonsensical numbers. i.e. I get a message failure because the phone tried to text "0110000100000" which is obviously not a phone number. I had installed handcent almost immeadiatly upon getting the phone. So I tried uninstalling it and putting on chomp. Still have the same problem. It seems to help if I use my task killer after using the sms app.

I am running the original firmware that came on the phone from Rogers, as everytime I use pc companion, it tells me i am up to date, and the update service locks up my computer (and my laptop and my wife's netbook).

I would rather not do a factory reset, but I am getting pretty close.
