i have an iPhone 3gs that no longer charges or syncs. It will still work with dock port accessories such as an FM transmitter. If turned off and connected to its usb cable (wall charger OR computer) it will turn itself on everytime. If turned off it will "trickle charge" very very slowly, approx 50% in 24 hrs.

This happened after a specific incident. The iPhone was plugged into an iMac's firewire port with a usb adaptor. Nothing seemed to happen, and afterwards an external hard drive was tried, and nothing seemed to happen. so everything was reconnecred via its normal USB ports but neither device was recognized any more. evidently the usb controller board for hard drive was fried and something of the iPhone's was too.

So what needs to be replaced?
my own research leads me to believe either the pmb6820 or the ltc4088-2.

What do you all say on it? where should i proceed?
