Till last week my iPod touch was working very swiftly with my PC. But from last week I am not able to connect it with my PC. I had already tried to establish both connections wired as well as wireless but I have not got any success on that. I had already reinstalled the software of iPod in my PC but still nothing happens. When I try to establish a Bluetooth connection my computer does not detect any external device. So I want to ask this from you guys, what should I need to do?
