I updated a friend's last night, haven't done mine yet. He had 4.0, and it insisted on upgrading to 4.1.1 first, then went to 4.2. Not sure if I screwed it up or not, but it said "Current version 4.0, newest version 4.1.1". I just wanted 4.2. Maybe when I do mine, I will get smarter about the whole thing.
