hi, i have had my iphone since october, the other day i tried charging my iphone on my ipod charger, because i was out of town....remember it was still the same connector.. well i left if on the charger for about 4 hours, and when i came back to check on it it was extremely hot, so hot to even touch and the screen was dancing around with grayscale lines.... well i took it off the charger and the iphone was non responsive so i put it on my iphone dock when i gfot home and everything seemed to be fine..... now i took it off the charger and the iphone battery barely lasted 10 hours on stand by time....... any suggestions on what to do or if i can do anything.... PLEASE HELP THANK YOU
