I just used it to upgrade from GB 219 and it seems to work fine
15 minutes, start of RSD to at ICS homescreen. Successful upgrade from stock GB219 to this fastboot.
Few things to note, for those that may ask:
I ran a Titanium Backup before doing anything.
I did not thaw any apps. I left all apps that I froze alone.
I left the device rooted.
I forgot to run Voodoo OTA Rootkeeper, so I can't comment on that >.>
I did not delete cache, data, or dalvik. I left everything as is.
After flashing the Fastboot, and booting to ICS, all my apps were intact. I can't find any that aren't working.
Test call and texts were successful.
Rerooting after ICS was successful.
So far, the only issue is Facebook force closing. But I'm sure a reinstall of that will fix it.
Definitely slow using at first, but most people know it will be as it updates system files and databases. Many apps decided to update after booting into ICS.
Overall: Success. If you don't want to wait for the OTA, do this.
Update: Found an update to Facebook in Google Play. No more force closing!

I'm glad it worked out for you guys. I didn't have time to post instructions, I spent most of my time answering other questions and left the SBF to the more experienced folks.
As far as Flash, it's not preinstalled and even if you download it from the market there's a 50/50 chance it will work. I think we just got to get used to it, the iphone never had it and Adobe is cutting support for Android.
