Well, the original iPhone had two front-mounted sensors - one proximity sensor and one ambient light sensor, to be more specific. Why would the 3G iPhone need an additional proximity sensor?
According to iLounge, the iPhone 3G will have better face proximity detection with the help of this additional sensor. Obviously, better face detection would make me think about an additional camera, so video conferencing can finally arrive on the iPhone. Unfortunately, Steve Jobs didn't say anything about a front-facing camera design at the WWDC, and this makes me wonder...
Do you think the 3G iPhone still has some hidden secrets? Is it possible to see Apple changing its product release strategy so much, that only part of the final features are revealed when announcing a product for release in less than a month? Feel free to drop your comments, because I have no idea, to be honest!
