Neo over at xda has a working AOSP Rom with working bluetooth. I haven't had time to flash yet, but looks promising! I just thought I'd share over here for those that have been waiting. If you flash and like, let me know your thoughts. I'm concerned about only ad-hoc tethering as I may need tethering to my iPad next week while traveling.
