Using it today, ive noticed no major issues except for a crappy wifi icon that doesnt work right. Beyond that it is super stable, not buggy, and works almost like 2.2.1. The first 2 were horrid, happy to report as of now everything works right.
Bluetooth A2DP works with my Motorola T605 handsfree, the dock connector audio out works with a single pairing (play song first, then connect to dock). All apps work (facebook, pandora, flixster, etc). Thumbs is up!
