There's a keyboard combination to press... can't find it with Google 
right now.

It fixes a few minor bugs. It adds absolutely no features or voices. If 
you don't suffer from these bugs, chances are you don't want to upgrade 
your AN1x.

Mine still has the original ROMs and I've never seen any reason to 
upgrade them.
