...Has anyone heard about a mod that will allow your audio from a phone call to play out through the dock connector ie. component A/V cables rather than just the headphone jack? I use my iphone 3g in my car as my media center along with my in dash tv to play all my music/videos and want to also hear my phone calls through my car speakers. I know that this use to be possible with the older 2.0 or 2.1 FW's since I use to do it (I think it stopped working w/2.2 FW) however the caller would hear an echo/poor quality sometimes. It worked well enough that I could deal with it over buying a bluetooth/fm transmitter though. Any advice on what files need to be modded to accomplish this?
