Already in November last year were talked about the fact that a beta version of iOS 5 will limit your ability to make shortcuts for the iOS settings without making jailbreak, and Apple did not change anything regarding this system. iOS 5.1 was released a few days ago and it prevents users from using URL-type shortcuts to open / activate various iOS settings.
By using this system we could activate Wi-Fi/Bluetooth, Airplane Mode, also could open various menus of the application Settings. Now everything can be forgotten because these things can be made only if we jailbreak our device.
Unfortunately until this moment no workaround has been found for this limitation imposed by Apple and it seems that in the near future there will be any unless Apple will modify the iOS shortcut system.
