Go-Dap GD-03 iPhone Amp/Battery Combo
This is a brand new, never opened GD-03.
iPhone 3G amp with 40 Pin connector. It can be modified with dremel to fit a iPhone 4 (4S) better and also fits first 3 (maybe 4) generations of iTouch with no modification.
Makes a nice portable or desktop amp.
Search threads on head-fi for more information about it.
I am asking $20 which includes USPS shipping to continental US.
