I've searched everywhere to find an explanation to my dilemma but couldn't find any answer so I hope someone can help me out here. I have a 3GS (less than a year old) that suddenly, out of the blue, will wake itself up and started dialing constantly. Luckily it dialed only to my spouse's phone number. The phone was sitting on the table and then woke itself up and started dialing. It happened on 2 different occasions already (today is one of the 2). The crazy thing is that it would constantly dial out, non-stop. The only way to stop it was to reboot the phone. Btw, the phone is jailbroken running on iOS 4.0.1. Any clue why this happened?
