Very cool. Thanks for the link, I'll try this sometime today!

I'm fairly certain my bootloader is unlocked. At least, I have the "unlocked lock icon." I guess that's the difference with purchasing it from Google instead of TMobile or AT&T...

I'll report back with my results.

*edit*
Just to be clear, am I resetting my phone with this tutorial? I get nervous when I see stuff like "flash recovery." What is the recovery image and what does it do?
