Flashed back to 2.1update 1 and now unable to pull the ota to 2.2 (2.3.15)

My buddy was running the leaked 2.2 (2.3.9) from the summer on his Droid X. He just flashed the 2.1 sbf to his phone and is now showing 2.1update1. But when he goes to system updates it says his phone is up to date. Anyone know how he can get to the offical 2.2 (2.3.15) build from here?
