Patazon Black Extension Dock Extender 30pin Adapter for iPod iPhone 4 4S
This item has never worked for me I have no idea what it does. If it explained what it did on the Internet but never did what it said it was going to do so it collects DOS on myself that's it have no idea what it supposed to do whatsoever because it has no use to me on the directions in which came with it and on Amazon.
