So yesterday, all of the sudden, my iphone isn't charging or get recongize by iTunes when i plug it on my iMac. Last night i connected it to my tv and it charged fine. Today i sold my TV and connected my iphone to my Mac and nothing. No sync, no charging. So i connected it to my Xbox and nothing. I though it was the cable so i got my old Nano that i didnt use in 2 years. As soon as i connected it it turned on and charged. So its not the cable and its not the usb port. I have been using my iphone alot more these days cause its the only phone i have now and i use it alot for internet at my new place. Can anyone help?
