This morning my iphone 4 suddenly stopped charging or connecting to my computer. It was charging just fine over night, and had a full battery this morning. I unplugged it and used it for a little bit and a few hours later i went to take a nap before work and plugged it back in and nothing. I tried connecting it to my computer, and nothing. Tried 3 different cables, and 2 different wall outlet adapters and nothing. Tried those same cables and chargers with my roommates 3gs and they all worked just fine. I tried it with my car charger and nothing. The only think ive gotten from it so far is my laptop at one point said that there was a problem with the device plugged in to the USB port, but now it doesn't recognize that it's there. Ive tried resetting, rebooting and restoring via the "erase this iphone" function inside the phone as i can't restore from itunes without it recognizing it. Ive tried both restoring to a back up and restoring to a new iphone and im simply getting nothing from it. ive also tried cleaning the connection, and blew out any lint with compressed air. As soon as the battery dies later tonight im sure i wont get it back on. Anyone have anything else i can try?
