The iPhone had already been announced and revealed during Steve Jobs' MacWorld keynote. To put it mildly, things have been picking up for Apple since then. But what more of it? ActionCorp has posted an interesting video that compiles four features that we may have missed during that keynote address.

As mentioned in the clip, these aren't anything groundbreaking, but they're still interesting to take note of. The simple fact that Jobs merely mentioned these in passing might pique your interests and make you hopeful that there probably really is something more to this:

• Calendar application - viewable by year, day, and month + buttons for notes and adding events
  
• Google maps - no interface for traffic and directions shown, but there are buttons that could possibly show this
  
• Letter scrolling - on top of finger flicking/scrolling, you can also simply click on said letter to jump on
  
• Ringtones - default ringtone heard + ringtones sold on iTunes

The video pretty much explains everything and gives sound basis for their speculations and expectations of the final specs for the iPhone. Check out the vid below:
