This isn't totally Mac-related, but I just wanted to report that I got the Jabra FreeSpeak Bluetooth headset for my T68i (which I of course Sync with Address Book via Bluetooth ;) ) a few weeks ago and it works great. The only caveats are related to range; I've experienced a significant amount of static in the following circumstances: - Anything more than 10-15 feet, unimpeded. - Having the phone in a bag with a lot of other stuff surrounding it. - Environments with a lot of RF interference (office with too much tech stuff, floor of Macworld Expo ;) ). But within those limits it works quite well. I generally keep my phone either in my pants or jacket pocket or in the outer pocket of my bag, and the signal is quite strong. Combined with the T68i's excellent voice dialing, I rarely have to actually pick up my phone.
