Based on my experience for the two minutes for which my device was jailbroken, I saw little difference between a jailbroken device and nonjailbroken device. All I noticed was a little Cydia icon. Presumably I can add software via Cydia, but I'm curious to know what else jail breaking offers out of the box on an iPhone 4 running iOS 5. Is Cydia really the only starting point, or do other settings magically appear in the Settings app or elsewhere? Are there other benefits?
