Lost the cable for my dads green 2nd gen ipod nano 4gb. http://cgi.ebay.com/ws/eBayISAPI.dl...0035&_trksid=p3907.m32&_trkparms=tab=Watching That says 2nd gen naon as well as 3g ipohne. But I thought 3g iphone was a different cable wasn't it? Different pin layout or something. Or will that work on my nano.
