Does anyone know if either of these products exists:

  1. Female dock connector to Mini USB (Like this, but with a dock connector instead of USB. DealExtreme: $1.45 Mini USB 5-Pin Male to USB A-Female Adapter)
  2. A female to female dock connector

Basically, I have an external battery for my iPod, and I’d like to use it with my multitude of devices that have mini USB ports.
