I had the same problem connecting iPhone with 4.1 (8B117) version to a Pioneer DEH P8080BT.
- Now only the phone (BT phone) works and reconnects automatically (as before). - BT Audio (that worked nicely in previous versions) now is impossible to connect!
Iphone Bluetooth screen is poor and does not offer control or information regarding what is happening. Time to move to Android? I hope Apple could do something quickly to fix this newly created problem, or replace the previous version that worked in a better way.
