If Engadget Mobile is correct, then yes, my XV6700 and yours too will have AKU 3 this spring. Some of the newer smartphones already have this Adoption Kit Update and it would be nice to see this upgrade make it’s way to the good ol’ HTC Apache variant on Verizon. If you’re curious what could potentially be in the upgrade, check out Paul’s write up from Mobius over at MoDaCo. The BT DUN going away in favor of the PAN profile has me wondering how much easier (or harder) it will be to Bluetooth tether the XV6700 to a UMPC.
Edit: removed link to hacked version. C’mon, you don’t want to chance a bricked phone, do you?
