Ok, good news is that I didn't nuke my phone. Bad news is that it didn't seem to do ANYTHING. I'm running the stock Verizon 6.5 ROM (work phone so no HSPL unlock, don't go there, please, just don't go there) and the latest installable SenseUI 2.5 from the HD2.

The cab installed just fine and asked me to reset. I did, it came up, I unlocked, I hit start, nuthin different.

I'm going to leave it installed and see if I can see anything in the morning after I've had some sleep.
