OK, I played all day with the 3500 build installed on my SX66. Good and bad news. The good news is that it paired with both my HBH-660 and my Acura's HandsFreeLink (HFL).

At first HFL would dial and answer, but the car's stereo wouldn't act as the headphones. For some odd reason it suddenly started working. It isn't 100% consistent. It always is capable of answering and making calls, but sometimes it will not act as the headphone. Very odd, I would expect the opposite. If it isn't being the headset I can say "transfer" which switches the audio between the phone and the car and that usually works. Once in a while when the car is doing the audio I can't hear the other end of the conversation. All odd.

My HBH-660 is not acting as good as it did on build 2400. I had the usual problems with connectivity before, but not this bad. Now the phone and headset seem to waver between seeing each other and not constantly, even during phone calls. I can't tell if standby mode is affecting it because it happens so often regardless of the phone being in standby. It even happens during calls, which is pretty frustrating. One thing new is the question mark within the headset icon. I hadn't seen that before. I get that constantly. Sometimes the headset icon dissappears entirely and sometimes it has a question mark in it. Either way this disables the ability to use the headset.

I did completely remove pairing and re-pair both devices to get this far. I will live with this until the next build. I would like the headset to work like it did before, but it is so cool to have HFL working in the car (albeit only about half the time) that I can't go back. People told me today I sounded like I was on a landline to them and they sounded better than ever to me via my Bose stereo. Incredible.

One question, why are the Bluetooth builds you are working on specific to CDMA? I would think GSM and CDMA would have little to do with Bluetooth. Anyway, if there is a difference I hope someone does all the great work you guys have been doing to a GSM phone to fix these issues for me. If you have any thoughts or suggestions, or hear of a new build, please let me know!
