It's been a while since I've been able to install apps from my SD card. I've tried many different ways of doing it, and it doesn't work. For example: Astro: I try to open the App manager or whatever through it, and it says that it was unable to mount the apk file. Apps like AppInstaller: I try to open it and it says that it was unable to parse the file. I have wiped/installed many times, since that's often been what BB has required, however I would really like to be able to install apps and want to know what the problem is.
