I had the chance to test with a 2011 PCM3 device (V2.20) and had problems connecting any of my Samsung phones (Galaxy S CyanogenMod/Nexus S) running rSAP 1.1. The phones are connecting but a few seconds later the PCM shows "not connected" although the phone is still showing an active rSAP connection. On the next attempt the phone connected with HFP. I could reproduce exactly identical behaviour several times.
If I manage to restore a stock Samsung ROM on my Galaxy S I'll try with that one, too.
When I tested with a HTC Desire it did not work as smooth as with my older (2008/9) PCM3 but it worked, including phone book transfer with PBAP.
