I had recently jailbroken my phone and it was working perfectly fine. I download Installous from Cydia and installed many cracked apps (about 20). I was using one of them one day when all of a sudden, the iPhone froze. I did a hard reboot and I turned it back on. All I saw after that was the apple logo, then the black screen before the password screen, and then the apple logo again with the spinning wheel. This pattern continued for a while. I tried several more hard reboots but the same problem continued. I connected it to my computer and then tried turning it on and it worked for a while. I used the same app and the phone worked fine. However, when I locked my phone after that and tried to put my password in later, the phone froze. I did a hard reboot and the same pattern of logo, black, then logo w/ spinning wheel occurred. Please help me. How do I fix this problem without doing an iTunes restore (I stupidly didn't back anything up.
