iPhone users can iOS 5.1 since their camera quickly booting ontgrendelscherm by the camera icon to sweep up. Are you still on iOS 5, because I would like your untethered jailbreak not want to risk, you have this icon appear still get through twice on the home button and then select the camera icon. The jailbreak tweak Camera Grabber allows you boot the new method can also be used without your untethered jailbreak of iOS 5 to give up.
Camera Grabber ensures that the camera just like in IOS 5.1 quick start up from the ontgrendelscherm. The camera icon on this screen to sweep up, start the Camera app and lets you start shooting. The icon is always on your ontgrendelscherm, so you do not get twice the home button you have to press.
This tweak works currently only under iOS 5. Too bad, because iPhone 3G owners can iOS 5 does not install, making it the shortcut on ontgrendelscherm the iPhone can not use.
