I have a first gen iphone and had updated it to 2.0. It got wet and would not restart so phone help had me hold down the two buttons and that worked but did not seem to be charging. Went to itunes and restored it but when I went to the next step I got a 1604 error. Took it into apple store but unable to help since it got wet. He did tell me the battery was taking a charge. Proceeded to try to uninstall itunes, restart computer, check usb ports, tried different computer (I am running windows xp). All I get is the apple screen or the itunes symbol with the cord. Now when I plug it into the computer nothing happens, screen remains black and won't turn on. It will work when I am plugged into the wall(get apple or itunes screen). Any ideas?
