I just inherited a Droid 2, and flashed Liberty 2.0.1 onto it the other day. The biggest problem I am having right now is trying to update a few apps that come stock on the Liberty install, Google Voice and OI File Manager. When I try to update these through the market the install fails, and gives the message "Package file was not signed correctly." I tried to uninstall the apps to reinstall, but uninstall fails on both of them. I've also tried reflashing Liberty, but that didn't seem to help at all. Does anyone have any idea why it is behaving this way? Fortunately I haven't activated this phone yet, and am still using my OG droid until I can get this new one fully set up.
