So far based on the description, the major functions such as WiFi, GPS, phone, audio, etc are working. Other features like its camera, USB tethering, FM radio, Bluetooth, etc are still in the works. For those who just want the core functions of the phone, it looks like this CM9 ROM ought to do the trick, but for those who want the extras, you might want to hold off on the update until a later build has been made available. For the download and for the instructions, head on down to the XDA forums. Once again, proceed at your own risk and always remember to back up your devices!
