I recently had a very unstable issue with my jailbroken iPhone 4. I used redsn0w to jailbreak the device. Everything was running smooth and great. Loved having my iPhone jailbroken! But for some odd reason the apps stopped doing the shake thing then you use the task killer or even go to delete something. Everything was glitchy and running horribly. I wanted to just remove the jailbreak all together. So I tried to restore my iPhone in itunes and all goes well. Gets to the apple logo and the restore bar. But it freezes 3/4 of the way through. I have tried everything and use this phone for a business. Any ideas would be so appreciated.
