Microsoft has updated the Bluetooth stack in Windows Phone 7.5, with the new stack receiving Bluetooth SIG approval on the 5th June 2011.

New is Hand-Free Profile 1.5, which should mean better support for Bluetooth car kits. Also updated is the AVRCP (Audio Video Remote Control Protocol) from version 1.0 to 1.3, which brings track and other meta-data information transmission and playback status information (paused, stopped, etc).

Unfortunately it still does not bring the stack up to even iOS 4 level, which supports Personal Area Network (PAN) profile, often used of peer to peer multi-player gaming and Human Interface Device Profile, used for Bluetooth keyboards and controllers.
