Id be interested to hear this one.. If you could no longer jailbreak future iphones, would you continue buying them? Personally id think about other phones at that point unless Apple added some of the same abilities with the firmware that you can do on jailbroken phones. Themes, privacy, background processes, calendar on home screen, etc etc... The list goes on. I think if they took that away, Id probably just go to a different company that would allow me to do more with my phone.
