Hi Nephros, sorry for mixing up things (A2DP and HFP). I never had big problems with HFP, not in version 3.4. I just tested this morning for you. Telephone connects, contact list is synchronized, recently called list as well. Voice recognition works, so the commands 'dial contact, etc. works). Also volume adjustment during calls from steering wheel. But if it is better compared to 3.4 is hard to say in my situation.
