    Default A2DP Bluetooth profile enabled in iPhone firmware 1.1.1

    When Apple released iPhone firmware 1.1.1 they may have inadvertently enabled a new, undocumented feature.

    According to AppleInsider, iPhone 1.1.1 allows you to stream all audio, including iPod songs, audio from movies and TV shows and even keyboard taps and system sounds to a Bluetooth headset. Previously, only phone calls and voicemail (when enabled) were streamed to Bluetooth headsets.

    Apple appears to have enabled the A2DP (Advanced Audio Distribution Profile) Bluetooth profile in the 1.1.1 firmware update. The only problem is that it isn’t implemented properly. While streaming audio to a Bluetooth headset iPhone simultaneously outputs the same audio through its built-in speaker, which makes the feature much less useful. Plugging in headphones only serves to cut off audio to the wireless headset.

    The question is what Apple will do to “fix” the bug. Will they silence the speaker when using A2DP or will they remove A2DP streaming for audio other than voicemail? I hope that it’s the former.

    I think it's there in 1.0.2 as well. And that it is NOT A2DP but plain mono ...

    Above poster is correct....1.0.1, 1.0.2, and 1.1.1 is using the headset profile / hands free profile.

    A2DP is a profile that specifies how "high quality" stereo, compressed audio is transmitted to a pair of headphones.

    A2DP is buried in the iPhone, but it is not implemented due to some goofy DRM-related issues.

    Lawyers are keeping you from your swanky wireless headphones

    Now...with a little work....its possible that a third party app could be written...although, it would require deep interfacing and muddling with BT. But efforts put into this would likely lead to other useful things, such as tethering.
