Whenever I plug in my (3rd generation, 8GB) iPod Touch, iTunes pops up an error message saying I need a new version of something called Apple Mobile Device Support. To get it, I need to uninstall Apple Mobile Device Support and iTunes and reinstall them. The only problem is, I've done that three times, and I'm getting the same error! Please help, I want to update to OS 4.0 when it comes out!
