What I want to do is have it so the camera application is always running in the background, so when I need to quickly take a picture I just go onto the camera and its ready. I've tried going on the camera then exiting via the red button, but that doesn't work. Any idea? Or will I just have to live with the loading time of the camera?

Cheers

load the camera app & then press the menu buton twice.

Thanks!! That works perfectly :D
