MacRumors has uncovered more evidence of an iPad 2 camera in the latest Apple iOS firmware. iOS 4.3 beta 2 has made its way into the hands of developers, and icons for Camera, Photo Booth, and FaceTime apps can be found in the release.
The icons appear in a small image (homeScreenOverlayFaceTime~ipad.png) which is used to preview iPad home screen wallpaper. In the current firmware iOS 4.2, this same file shows all of the standard iPad icons but these three camera-specific apps are missing. It's possible Apple could ship the iPad 2 with only one front-facing camera, although other evidence points to two cameras on the iPad 2.
