I'd like to have an app (or whatever gets the job done) which fixes a bug in the Bluetooth functionality of the iPhone. This bug has persisted through iPhone gens 3GS/4/4S and through many iterations of iOS, yet Apple has not fixed it for whatever reason.
When a bluetooth device (car radio, headset, etc) and the iPhone/iPad connect to each other, the A2DP (advanced audio distribution profile) within the Apple device automatically tells the Apple device to start playing music. This should not be the case, or at least there should be an option within the Bluetooth settings of iOS to turn off this autoplay. Third party attempts to resolve this (BTServiceManager via Jailbreak) completely disable the A2DP, which is like taking a hammer to the problem instead of a scalpel. I would like to have a solution that toggles between autoplay, without having to disable the entire functionality of the music playback.
I suspect the app would be delivered through Cydia/Jailbroken iPhone, which is fine, unless you can figure out a way to resolve the bug without having to jailbreak the device. I'm very interested in fixing an annoying bug that me and many bluetooth device users experience, and then sharing it with the world.
