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.

With the new accessory access APIs announced as part of iPhone 3.0, however, it looks like we will be seeing some amazing new stuff coming our way... at some point.

What would you like to see?

iPhone 3G uses Bluetooth 2.0 + EDR, but it seems like the folks behind the BT standard are ready to release the next big version, coincidentally sharing the same 3.0 version number as the next iPhone firmware update, coming this summer.

There's been no word on Apple adopting Bluetooth 3.0 for iPhone OS 3.0 or the next generation iPhone hardware expected to be previewed at WWDC in June, but according to BGR, it will be landing on April 21st and will enable:

Ultra-wideband (UWB) wireless technology to achieve transfer speeds of up to 480Mbps. No, seriously. Higher transfer speeds are actually achieved by enabling 802.11 standards when heavy lifting is involved and then switching back to an older, slower standard when big transfers are completed.

Of course, Apple's track record when it comes to BT is not good, so there's no saying whether or not they'll make the jump to Bluetooth 3.0 now... or wait for 2015 to roll around...
