Why (rhetorical) do people bother to Jailbreak their devices?. I mean SERIOUSLY?. Apple design a lovely clean UI, with simple, attractive icons... and then some Failbreaker comes up with... THIS?! 
I can totally understand wanting to unlock an iPhone to use another network, but Jailbreaking just opens the whole device up, in a way it is not supposed to be opened up, exposing it to lagginess, crashing, memory leaks, UI inconsistencies (looks and feels broken) and possibly a lot more I haven't thought of yet.
I once Jailbroke my iPod touch, to see what all the fuss was about... and was disappointed with all the inconsistencies, tbh. I even managed to get root access to iPhone OS terminal, and ERASE THE WHOLE OS!.
Fail!!
