Well finally an official MR2 update has started to roll out. @teamandirc got his hands on it a little early and a rooted version has been created. In my opinion, the best feature from this OTA is the new radio. It will work on any gingerbread rom, like Das BAMF 3.0, so there is no need to flash leaked radios anymore. Check out the link below for the full rooted rom and radio.
Update: Radio Pack is now updated to include this radio.
