I discovered something this morning that really makes me disappointed with 1.4 bluetooth headset support. We seem to be losing features.
Previous to 1.4 when I had an incoming call on my Pre, I would hear a tone in my bluetooth headset (Aliph Jawbone Prime) and I could answer the call by touching the headset unit - just like every other bluetooth headset on the market. I would also be able to hang up using the headset.
Now, no ring indication through the headset and no ability to answer or terminate calls from the headset. This doesn't work, Palm, please fix it ASAP.
