Please help, yesterday I noticed my iphone was not charging on my car charger. I brought it home and it will not charge on the coking port or on the computer. I get an error message that USB device Not recogized. Anyone know what to do? The nearest apple dealer is over an hour away and I need my phone for work, Im always on call. If I have to send it off I dont even have a sim card to activate an older phone while mine is being repaired!EERRRRR Help!!!!
