I just recently rooted my droid and I am running smoked glass 6.0. I keep trying to download google maps 4.2, root explorer, google goggles 1.1, and facebook 1.2. But everytime I download them it says "package file not signed correctly" and they wont install. I read and saw that if you delete the original version and install the update it would work. I was getting root explorer to do that but it wont even install! I downloaded File Manager but everytime i try to delete the above apps it says "insufficient permission." So then i download ASTRO File Manager. Everytime i try to delete the above apps with that it says "uninstall unsuccessful." So I need some help please. I like to use these apps and I just want a way for them to work and be able to update. All 20+ other apps i have work and installed fine by the way.
