That night itself I installed Cylay, a security app, and it asked me to reboot. When it reached the apple logo screen, it froze and the only way to get it our of that state was to put it into DFU mode and restore it. I did a bit of research and found that many people are having that issue. What I was wondering was, what is causing this to happen? Is there any way to prevent it? If it's completely random, and there's no explanation for it, I don't think it's worth jailbreaking my iPhone. Any thoughts? Thanks.
