This tweak enables widescreen photos in the built-in Camera.app on the iPhone Touch 4G. It effectively adds more megapixels to the resulting photos, at the cost of losing the traditional 4:3 aspect ratio.
Because of that, this tweak also adds a button to the camera.app that toggles the tweak in case you would like to retain the original ratio. There are no icons installed for this item, and no settings to configure.
HD Photographer is available for $0.99 in Cydia Store via BigBoss repo.
