Looks like a ship date of late April.

Gah! I just bought a 640, I didn't know this was coming out. Unfortunately I'm too lazy to return this one and spend an extra $50 for the upgrade so I'll just stick with what I have.

Does the 640 loose its pairing as often as the 510 does? My Jabra hardley ever lost its pairing but my 510 drops 2-3 times per day. Hopefully the 645 won't have this problem.

Have you tried replacing your 510 with another one? I've had the 510 for about 3-4 months and never get a disconnect. Just a thought.

No I haven't. I will give that a try this weekend.

I haven't had any pairing problems with the 640 at all.

I have not had any pairing problems with 640 and 8700. However, people say my audio sound tinny like in a large room. It worked fine on my Razr.
