Today, in the wee hours of the morning, Cyanogen tweeted what many people have been waiting for: video footage of CM6.1 up and running on his T-Mobile G2.

His explanation for how things work:

Basically what I'm doing is temprooting and rebooting all of userspace with CM on the sdcard. Gonna keep refining it while the really persistent and smart guys from #g2root keep working on a permanent root.

And there you have it. We wouldn't expect to see a release until a permaroot is established, but it looks like things are definitely moving along nicely. Video:
