iphone camera application

iphone camera application. 4.3.1 Xcode project, well commented. Only using public apis. must be accepted by the app store. All rights to the code and project belong to me (the purchaser) and can not be resold to others. copy of Apples camera app with the ability to add new features. Need an additional button like the “options” button. when it is "single finger double tapped" it becomes highlighted and then by pressing on it and holding it, the button can be moved to any location on the screen. Once "single finger double tapped" again it becomes locked in that position and saved. (until the process is again executed). Must be able to hold the new button and determine if the phone is being slightly rotated to the right or left. if tilted to the right, the app will add an effect to the image, if tilted to the left the app will subtract the effect from the image. the app must be able to programmatically access the zoom in/out feature of the camera to help create new effects.
