Anyone else having this issue? After updating my iphone 3g to 3.1 (and waiting for-freaking-ever for it to backup) and seeing everything was working fine (Safari seemed snappier ;-) )I went about my day. Made a stop at the bookstore and was going to whip out my phone to check amazon prices when lo and behold my phone would not do anything. Wouldn't respond to me holding down the home key or the power key. It did reset after doing a reboot (holding both the home and power button for 10 seconds). It happened again on the way home so I decided to plug it into my macbook to "wake" it up but absolutely nothing happened. I have hardware growler installed to see what gets plugged into my macbook and nothing popped up. I unplugged it, pushed some buttons again, messed with the silence switch a few times and nothing. The weirdest thing happened a few minutes later. The phone started vibrating and the screen kept turning on and off. It was like it was finally responding to all of the input I had given it a few minutes minutes earlier. So anyone have this happen to them? I'm going to restore it to see if that fixes it. Also another wonky thing I had happen was the auto-dimmer never undimmed until I locked the screen and unlocked it. Oh and btw, the battery is fully charged.
