I've been having trouble with my iPhone 3G. It can't be turned on unless it's plugged to a wall charger. When it turns on, it shows me the Apple logo for like a minute then the "Connect to iTunes" screen. Whenever I unplug it from the wall to plug to my laptop, it dies. It won't turn on when I plug it to my MacBook. I was hoping restoring the device would fix the problem but how am I supposed to restore if it won't turn on when plugged to my laptop?
