I bought it thinking that it would fix my -iphone 3gS incompatibility with my iTrip car plug fm transmitter issue.. but to no avail.
Hope he one day writes a program that would solve this issue.
I hear ya. After my new 3Gs (from the original 2G?) I've found most of my charger/cable/transmitters no longer work. I do understand licensing, but this is annoying!
i just got the latest update... it works even better now! I can play out of programs that didn't support it before... definitely worth the $2 and the $4 cable. i also got this guy's 'music controls' program... pretty cool too (I pandora ALL the time and text... it's great :) )
