iPod iPhone iPad Extension Cable (BLACK) 36" Extender 30-Pin Male to Female Dock Connector AUDIO, VIDEO, & CHARGE TRANSFER
I ordered this to hook my new ipod 4 up to my ihome clock radio to charge without taking off the case.  The cord was cheep and flimsy.  It did not secure to my iphone and did not work.  I returned it and got the similar cord that cost 14.95 which works fine, although I would prefer a black cord.
