Hi, I have an iphone 3gs running 3.1.2 and my home computer is running windows xp sp3 with itunes 9.0.2. I had internet tethering working by installing "mms and tethering settings" from the sinfuliphone repo from cydia and I was able to tether to my pc using both 3g/edge and wifi over a usb connection. I had to reinstall windows xp and now my tethering does not work. When I turn on tethering I get a message saying "fatal error during install" for the apple mobile device ethernet driver and the driver fails to install. I have tried uninstalling/reinstalling itunes as well as just the apple mobile device installer itself. I have itunnel but I want to figure out why normal tethering from my phone (without the use of itunnel) does not work. Just to emphasize that it was working until I reinstalled windows xp. Any help would be appreciated. Thanks!
