I'm running Windows 7 32-bit, my Iphone 4 won't connect to my computer. I plug it in and it plays the USB connected sound and then about 4-5 seconds later it plays the USB disconnected sound. Nothing appears different in the device manager. The big issue though is, I have an Iphone 1G, it connects just fine to my computer. It shows up in the device manager and Itunes recognizes it. Any suggestions? I tried uninstalling and re-installing. Nothing has worked so far. I want to sync my contacts and stuff to my new phone.
