One particularly interesting feature rumored to show up in an upcoming iPhone release is video conferencing. What is a simple feat for a webcam and Skype-equipped PC isn't as easy for a cell phone, albeit it is not new either, and Apple has recently applied for a patent that indicates future iPhones will include such functionality. The patent describes the phone being used for a variety of video-oriented services, from digital videos to photography, and specifically mentions video conferencing.
Many iPhone users have complained to Apple about the lack of video conferencing in a phone that is clearly capable of providing it. For whatever reason, be it cost or practicality, it hasn't been included, but I wouldn’t be surprised to hear that new iPhones will come stock with the feature. What else would you like to see in the next iPhone?
