We mentioned Bluetooth 3.0 before, and now it looks like the spec is getting a tad more specified. WMExperts has the story covered but suffice it to say it's stronger, better, faster, longer. (Or at least it borrows 802.11 WiFi power when it needs to be).
Lot's we still don't know, however, including whether by some miracle Apple could have it ready -- or at least ready to be upgradable -- by the time we get some new iPhone hardware this summer. Also, whether or not we'll be able to use BT 3.0 for wondrous things like wireless local syncing of ginormous media files.
