On Tuesday, January 15, Apple's top exec Steve Jobs gave a keynote address at the Macworld 2008 convention. Key among his comments was that in the first 200 days on the market for the cutting-edge iPhone, Apple sold 4 million units.

With 20,000 more units shipped each day, the iPhone currently has just under 20% of the U.S. smartphone market share.

Jobs promised that the iPhone software development kit will be released within the next month, allowing programmers everywhere to start developing great new features to integrate into the iPhone.

In the meantime, Apple released Firmware version 1.1.3 and is soon to be introducing a whole bunch of new features into the product including:

• Web Clips - a GPS-like update of GoogleMaps that allows user to triangulate their location
• The ability to send an SMS out to multiple recipients
• A customized home screen

Jobs also made mention of how many of the iPhone's features like mail, notes, weather, and stocks are now being made available in the iPod Touch.
