It's Official ... I have gone through 3 AA&T tech representatives and they patched me through to RIMM, where I spoke to 2 senior techs. You can not press the "Talk Button" on a new Jawbone 2 and have it activate Voice Dialing.
BlackBerry, according to the Wall Street Journal, now has 42.5% of the US market share among the "Smartphones", making it number one in the USA. It is simply stunning that the Jawbone 2, arguably the best Bluetooth earpiece on the market right now is incompatible with the 8310 Curve. It will pair, it sounds great, looks great, but do not expect it to function as the Motorola products do by interfacing with the Curve in the automatic voice command feature; simply not going to happen according to RIMM. Anyone and everyone, including ALIPH, the manufacturer of the Jawbone 2 is welcome to respond, but I got it straight from RIMM this afternoon, and the Jawbone 2 is not going to activate the voice dial feature for you.
One more thing, both ALIPH, in their support area and AT&T, through my personal conversations with their techs are badly misinformed about one other suggestion. Two AT&T technicians told me that rather than save the phone number on the SIM card, you had to create a recorded voice tag on the 8310 to get it to work with the Jawbone 2. Guess what? The 8310 has no provisions to create a recorded voice tag. The whole idea was to make the voice dialing part on the 8310 easier, so the old architecture of recorded voice tags has been eliminated.
There you have it; everyone can now stop trying to figure out how to make a Jawbone 2 activate voice dialing. The only way to do it is to go to the 8310 home screen, press the trackball over voice dialing manually and then tell it what to do through your BT earpiece. (By the way, my ancient Motorola HS810 works beautifully with the 8310 - all functions) I thought I was upgrading by spending $120+ for the Jawbone 2 ... save your money if you have an 8310 and you want to use the Jawbone
