Just had the new PCM update on my 997.2.
Coincidentally have been trying a Tune2Air BT dongle with iPhone 4S for music streaming as an alternative to leaving a spare iPod permanently connected.
Spotted two interesting/useful things, Following the update:
1. Messages from CameraAlert app are now 'streamed' through the car audio, which is marvellous as they're much more audible as they get treated via the Bose audiopilot
2. Conscious that most of us don't have DAB, tried running an iPhone radio app, AND IT WAS STREAMED TO THE CAR AUDIO, in preference to the iPhone music. (And reverted to iPhone music if I stopped the App)
Minor glitch, which is that the two BT profiles (audio and phone) appear to fight and so I'm getting small dropouts.
However, this seems to be a pretty reasonable way to get any internet radio station via the PCM.
