I constantly get an error from installer when I try to download an app. The error message pops up after I click install, it reads "Package download failed!" I was thinking of just restoring and jailbreaking my iPhone and starting over from there. I also tried turning my phone on and off, that only worked once, and I tried to refresh the sources a number of times. I have no clue what it could be. Can someone please help me with this issue.
