Vincent Nguyen, writing for My iPhone, explains “a few more things about the iPhone. There are four key items discussed in the video, calendar application, how to view traffic on Google Maps, another method of scrolling through long lists and finally how the ringtones play a role in iTunes and the iPhone.”
“Steve Jobs did not demo the Calendar application because it was not completed in time for Macworld. The speculation around adding new events on the fly seemed to be ‘no, calendar doesn’t allow creating new events on the fly.’ In light of new information, there’s a ‘plus’ button on the upper right hand corner of the application. We can assume pressing this button triggers the action of adding a new event,” Nguyen writes.
More buttons located and discussed, with screenshots and video, here.
