Video recording expected to be a key marketing point of the next iPhone already has an interface implemented within the iPhone 3.0 beta firmware, reports claim. The option is not enabled by default, but can allegedly be turned on by modifying configuration files. Once files are edited, the firmware is tricked into thinking a video camera is present.
The video interface is in fact a subset of the normal Camera application, toggled on with a switch in the lower-right corner; a Record button sits on the very bottom. Further investigation into configuration files is said to reveal autofocus support, as well as a variety of non-imaging related features. These include a digital compass, which could be used in turn-by-turn GPS navigation. More ambiguous is a "Voice Control" field, which may suggest the presence of built-in voice recognition. While a number of other cellphones support voice dialing, the feature has been conspicuously absent from iPhone firmware. Third-party apps such as Google's search software, however, have exploited limited voice commands under iPhone 2.x.
