Well, this happened a few days ago... Basically, I was forced to do a hard reset and I re-installed most of the apps that I had before. Now, every time it gives me the "update available" notification, it says that I always have one more than there are available. For example today, it said five updates are available. I click it, and it leads me to the downloads page and there are only four. It's starting to bug me...is there some random app that installed by itself?
