So i jailbroke my iPhone 4 6.0.1 using evasi0n and everything was going smoothly until I booted cydia for the first time. a screen popped up saying cydia was initializing or installing packages or something. it told me to wait and cydia would exit automatically. being the idiot that i am, i thought it got frozen and exited cydia before it could finish. my phone rebooted and when it did all my default apps (settings, phone, text, clock, maps, etc.) were deleted and the only thing that remained was the apps i had downloaded. i tried again and managed to jailbreak it successfully and now i have cydia, but not much else. i have tried restoring a back up and restoring it to factory settings, all to no avail. anybody that can help, it would be much appreciated
