I did a search and couldn't find the answer so apologizes if this has been discussed 1000's of times. I have an iPad 3 running 5.1.1 and i'm considering JB so I can keep it on iOS 5. My reason is that it runs great on iOS 5, no keyboard lag, no stuttering animations etc. Are there any security issues with that JB/OS seeing that it's considered an out of date OS? Is it easy to JB? Can I JB and jump back and forth if a JB release is available i.e. 5.1.1 --> 6.1.3 -> 7.0.3 -> 5.1.1? I realize there probably isn't a JB release for iOS 7, just asking a hypothetical.
