I have tried 3 different cables on my computer. A brand new Belkin wall charger from an At&t store. A used classic 80g iPod cable. A new 3g iPhone cable. All of these cables give me the unknown device error msg on Windows 7, Windows XP Home Edition, and Windows Vista. This is my first iPhone (new warranty phone from a friend) and I'm not impressed with the compatibility. Any suggestions?

Custom build, Windows 7
