Whenever I plug in my iphone 3gs to my computer, it says that the drivers failed to install. It shows up in itunes, but no in my computer. I'm running 3.0 and I did the restore trick the saurik posted. It has worked on this computer before, but not since i installed itunes 9.0.1. what should i do to fix this problem? btw, i have a pc running vista. Come to think of it, I installed Service Pack 2 today also, could that be part of it?
