I have a jail broken iPhone 4S and before, it perfectly synced with my iTunes. But since I updated my iTunes to its latest version, my laptop which runs on windows vista doesn't detect my iPhone. It says "apple mobile device driver software installation failed". I tried reinstalling iTunes but still, same problem occurred. Also, I tried restarting the device driver in the administrative tools but still, the problem wasn't resolved. Any help fixing this?
Also, I may have edited my windows registry to resolve my issue with iTunes with it's CD/DVD driver. Could this be connected to the error?
