this will show you how to enable the camera in your ios5 iphone lockscreen.
this is for ios 5.0 only. if you have ios 5.1 or ios 6 then please see this post
the camera icon is missing from the lockscreen until you:
- in the iphone lockscreen double tap the home button.
- you will see the camera icon.
FAQ:

its possible, with an update :D
2) how do I zoom in the camera app?
