My iPhone 4 is stuck on loading screen?
My iPhone is Jailbroken and I was trying to install something from Cydia and then it let me to a light black screen. I couldn't do anything when I had the light black screen. So then I waited to the battery get dry, and when I charged it back on, it had the Apple's logo, then it led to the loading circle. After 5-10 minutes of the loading circle, it led to the Apple's logo again and then led to the loading circle. This has been going for about 4 hours or so. I tried holding the power button and home button for 10 seconds. It does the same thing. It led to the Apple's logo then the loading circle. What can I do to fix this?
