Hey I'm new at jailbreaking, having only been broken for about a week. This morning Cydia crashed while I was adding a new source and it sent my iphone into a reboot. Now everything works fine except I can no longer access Cydia! It opens and states "loading Data" but turns off before the Cydia home page comes up. Any suggestions? I have an newer Iphone 3G with 3.1.3 fw that I used redsnow to jailbreak. Please help, i'm not done playin with Cydia yet!
most likely you'll have to restore, and rejailbreak. if cydia isn't working, im afraid its probably corrupt and you cant exactly fix it without restoring. Good luck.
