Since I've updated my iphone with 3.1, I have came across an interesting problem. It does not happen all the time, but it happens enough for me to notice- When I disconnect my iphone from the charger cable, the phone shuts down. It requires me to press and hold the "home" button and the "esc" button to perform a re-boot of the phone. I then have to wait the two or three minutes while the phone boots inorder to use it.
