I can agree with that. just got my phone back to normal ( and I DIDN'T HAVE TO FLASH SO THERE:P )
Many people wont have backups to revert to though, so whatever you do DON'T mount /and onto /home then run the remove /and command.
Also a good idea is to wait until you get home and read what you are doing properly, instead of copy/pasting any old nonsense into x-terminal while walking down the street

Now I got everything back running normal I think I'll wait until I get home tonight before trying N11
