When you go to Options > Advanced Options > Applications
It shows a list of all your installed apps. What does it mean when a particular one is highlighted in bold? I have Slacker and Google maps highlighted in bold...
I just looked at mine and it appears that those bolded are installed applications, as opposed to those that came pre-installed.
On mine, there is other software that I d/loaded but those seems just to be icon shortcuts to web access for the site, such as SouthWest, Youtube, viigo.
Not positive, but it seems like a reasonable explanation.
