Correct me if I'm wrong, I assume it's not that different from Android with the exception of being shitty.
You only require root/jailbreaking when you are using functions that are locked down by default, such as memory editing.
Any released hacks you find is likely an apk or the equivalent for iOS.
Which you shouldn't need jailbreak for, but then again, Apple.
Are their devices locking the installations if you haven't downloaded it from iTunes?
(Just get an android)
