actually, just make sure you flash it from recovery mode, I tried flashing from the clockwork app and it hung at the startup screen and needed to be reflashed.
I'd back up your existing ROM first and then go into the recovery and flash it from there after I knew I had a backup, plus as a previous poster said for some reason it won't go to the recovery console unless its plugged into USB which freaked me out a bit, thought I'd properly bricked it.
cool
what app did you use to flash from recovery, something similar to odin i guess? but for the nexus




I only have just over 2GB for now til I can decide to spend some money to increase it.
