You can still use Pandora over BT audio streaming you just wont have the interface. I certainly wouldn't let the lack of the Pandora interface stop me from getting the new phone. Especially sense Pioneer may actually have their act together and have an update for Pandora link for the new phone eventually.
This is good news, I really wanted to have the Pandora feature weather via BT audio streaming or the APP once its available. I have made up my mind on getting the IPHONE (4thGeneration ) : ) I hope that Pioneer will surprise us and tell us that they have been proactive and are already working on it. Apple must have told developers who have created recent Apps about the new interface. Either way, I am weary about the connection, I've had different generation I-touch's that charge on some devices made for earlier generations, but will not charge the newer ones? Hope this is not the case here.
