How long should it take to update after the download has finished and the iPad starts to update. Mine has been stuck with the progress bar on the boot-up screen half way across for about 20 minutes.
Did I just brick my iPad? How do I get it to work?
EDIT: Never mind, I finally just gave up after 30 minutes passed and reset the iPad and now I have to go through and restore the entire thing. I suppose that includes trying to update to 4.2 again. So much for Apple products always "just working" like everyone says.
