Sometime this morning after I got my PB set up, I decided to check the software updates, just to see. It said I had the current version installed (1690). Well getting home this evening, I decided to check for software updates and now it's saying there's a 2 MB update with the same version number (1690). I also hooked it up to my computer and it says that I'm up to date. I'm finding it odd and don't want to install it. Anyone else seeing this update?
