I have a new iPod Touch. I call it a Gen 3 but some people claim there is no such thing and it is a Gen 2. Anyway, can anyone point me in the direction of an external battery back up power unit that will allow me to still use the iPod's audio jack at the same time. The external battery pack I had for my old iPod Video doesn't work with the new Touch. I purchased a new unit from The Source (i.e. Radio Shack) and I had to take it back because the stupid thing covered over the audio jack. How stupid is that? I want a unit I can pop AA or AAA batteries into because I have plenty of rechargeable AA and AAA batteries around the house and besides, it would allow me to use disposable alkaline batteries in a pinch. I can't believe it is this hard to find accessories for an iPod after owning an earlier, and much more supported version for years. I'm absolutely stuck on this one. Thanks in advance.
