Is there anyone else with this problem? every time i try to access the camera on the lock screen via double-clicking the home button then pressing on the camera icon, it brings up the camera but when i go to take a photo by pressing the + button on the volume controls. it doesn't work! is there a fix for this? btw my iPhone is jailbroken on 5.0.1 via redsn0w 0.9.10b3.
