When TBT was introduced at the preview of the new SDK for 3.0 i was very excited. But i have a question is anybody working on an App that has true TBT functions? Because if you are i would like to add a suggestion. When i am in the car i usually have my iphone hooked up to the radio so i am listening to my music from my phone! Anyways if you are running lets say a Maps app that has TBT on it could you make it so that you can run iPod and the Maps App at the same time so that for instance if you have to make a turn soon the music from iPod will just fade out and the speaker telling you directions will come on and then when they are finished the music fades back in. That would be amazing! Just a thought!
