Sony Ericsson Xperia X10 :: Calling Wrong Person From Call Log

the phone constantly calling the wrong person from my call log, i can live with, angry as it makes me, i live with it. the phone just topped the list with this act. i had the screen locked. phone hadnt been used for almost 30 minutes. i plug it into my charger, and i hear a ringing, i look the screen is locked but lit up as it does when i plug it in, and the phone call handset picture is on, the piece of **** crap had started to call someone. and this was a person i had called almost 11 hours ago and ive since made a half dozen calls to other people. i had to pull down the drop down menu to end the call. yeah real nice getting a phone call at 1245 in the morning. **** me, im calling rogers and loosing it on some ***** call center rep tomorrow. i can see the phone acting out and freezing and lagging, but calling people on its own because i plug it in to charge.
