Maybe I missed something but this is reallllly poor:

I just did a factory reset in order to sell my PB, but in cleaning the screen the initial setup screen popped up and I guess I hit the French language selector while wiping the screen. There is no "go back" button to fix this error (FAIL!), so it appears I have to go thru the ENTIRE new product setup process including downloading the 300+ mb OS update (even though I just updated to the latest one 15 mins earlier!!!!). I now have to wait forever for the wifi download to finish before I can do yet another security wipe and start over.

Seems the PB is like the BB phones: when you do a reset (or battery pull) the unit gives you no choice to leave it off, it just automatically restarts. This is annoying in my case because I want to deliver the unit to the new owner in factory-fresh startup condition.

Big fail.
