I restarted my phone this morning only to discover NFL Mobile, Skype and Slacker Radio icons on my screen...I was in disbelief that Verizon would actually put more apps on the Phone the way they did for Bing - but then I checked my friends blackberry and its the SAME THING
They're download link icons pushed to your bb by your carrier. The applications cannot be installed unless you do so. If they are not in your Applications Folder they are not installed. Create a folder and put them all in it and hide the folder.
