Here's a bit of surprise, evidently that earlier hack we posted also works on the Samsung Focus. You first need to alter the registry to "unbrand" the phone using SamsungRegistry.xap, but once doing so combined with this trick, gave user John973 at XDA to the "March update" aka NoDo.

He's up and running as can be seen from the screen shots he took of the update process and "device info" screen confirming he has NoDo on board. Anyone else feeling risky?

Update: Raphael Rivera has modified the registry app to sideload; change string value to '000-88'

Update 2: The whole process take about 10 minutes and is a little tricky but it totally works. Of course, you'll need a developer unlocked device and some patience. The process is painless though as our device was left exactly as it were before we flashed, so kudos to MS for a smooth updating process.
