I basically tried some random ones, but the ones that intelliscreen needs to work won't work either. Activator gives me this error, anything related to messages+ and intelliscreen does. If try to install intelliscreenx 7 it says its dependencies iOS 5, 6, and 7 Library cannot be downloaded. When I try to download iOS 7 library it says it depends on Messages+ and Activator. Messages+ depends on Activator, iOS 5, 6, and 7 Library. Activator depends on Flipswitch. It's not finding the file for any of these things and I don't know if its a server issue or something with my phone.
What is the most recent version of Cydia substrate? Possibly my phone isn't detecting it. Reddit suggests running iCleaner on Cydia. I'm trying that out now.
Edit: iCleaner worked. When I refreshed my sources it found an update to Substrate. Weird how it doesn't find it automatically.
