How to free up space using MobileTerminal.
1. Download from Cydia MobileTerminal, syscleanpro and clean up crap.
2. Run mobileterminal and write su press enter then write alpine press enter. Now it should say that you are in your phones mobile root.
Write syscleanpro press enter and follow the instructions on screen. It’s a matter of saying yes or no to delete languages and keyboard languages. English is protected so I only say no on Swedish. I also say yes on moving my fonts folder.
3, Same again mobileterminal, write su then alpine then cuc and let it do its work = )
4. Get Daemontools from Cydia that does the work when it’s installing then it will ask you to reboot. Then done = )
Any questions just ask. None of this will be visible in the phone except mobileterminal.
