Just got a 16 MB iPod Touch and cannot get it to work at all. I turned it on, got the graphic showing to use the cable to connect it to iTunes. Connected the cable to my Mac USB port and the iPod touch beeped and then shut off. Turned it back on, again after about 10 seconds got a beep and it shut off. I tried every USB port on the Mac and the touch did get a full charge but never showed up in iTunes. It just beeps after about 10 seconds and shuts off. Am I missing something or do I have a defective Touch? Thanks for the help.
