Just letting everyone know of a new app that I have found. The App is called Resupported and it will bypass the security check which makes the iPhone or iTouch incompatable with video out and the Avic D3 ipod cable. The one catch though is that it is only on Jailbroken devices and it does cost $1.99. I have been using it for the last few days and it has been working great. I did not write the app so don't blame me if it doesnt work for you. One thing I have noticed is that if I use my passport to charge at the same time there is alot of interference. The app is currently only available on cydia at this time. Good luck guys........Also there is no reason that this shouldn't work on any device that has the same capabilities as the D3 and is also lacking a proper chipped cable.
Mods if you can sticky this it would be great as I think alot of people are looking for something like this.
