Instead of using the Volume Button to take the picture, i want it to make it zoom in/out. This used to be possible with an app called CamVolZoom. BUT THIS HAS BEEN REMOVED FROM THE APP STORE, so dont recommend this to me please. I'd to know, without jailbreaking it, if theres a way to do so. Whether theres a simply switch to change it in Settings, or if theres an app. Please help! Thanks
