What if a miracle happend and Apple looked at all the JB apps and brought it to iOS. So the messaging system was like BiteSMS with custom tones and all. There was lockinfo type info on the lockscreen which you could customize through settings. There were themes which you could apply using the "Springboard" app. There were user developed themes sold in the app store. The swipe across the top bar brought down the settings menu allowing you to turn settings on and off easily just like SBSettings. The million dollar question would you still jailbreak? Why?
