I have a brand new Itouch 3G (32 gig). When I first got it, plugged it into my IMac. Itunes launched and recognized the device, I set it up and downloaded apps and some of my music. No problem. 1 week later, I plug my Itouch back into my Mac and while I hear a "beep", Itunes does not recognize the device; therefore I cannot download anything to it. I'm running Itunes 9.0. For kicks, I plugged in my shuffle and Itunes recognized the device, no problem. At work, I plugged my Itouch into my IBM computer (running Windows 2000) and while it will launch Itunes, Itunes immediately freezes and I must force-quit Itunes. I am able to launch Itunes without the Itouch connected and download apps, etc., but as soon as I plug in the Itouch, it freezes. My Touch is not jailbroken or otherwise tampered with. Can anyone help me?? Thanks for your time.
