MacRumors reports that iOS 4.3 Beta 2 includes and image, under the sheets, of a few new iPad icons that we haven't seen before. The image is of the iPad homescreen with 3 new apps. Facetime, Camera, and even Photobooth are included in this firmware.
Now this doesn't mean that the iPad 2 will have a rear camera, but it definitely means that it will have a front. You will now be able to cross-Facetime with all the other iDevices including Macs. I don't think Apple would have let the iPad go without a camera for another year.
The article goes on to say that there were filters included in the firmware as well "Thermal Camera, Mirror, X-Ray, Kaleidoscope, Light Tunnel, Squeeze, Twirl and Stretch". These are presumed to be for Photobooth, which should be somewhat similar to what we see with the Mac app.
Well, we did it everyone, the iPad 2 is now officially getting a front facing camera!
