Jobs: iPhone has 19.5% of US smartphone market

In his Macworld 2008 keynote Tuesday, Apple CEO Steve Jobs told the audience that the company has sold 4 million iPhones in the 200 days since it went on sale.

Apple is shipping an average of 20,000 iPhones each day, and in shipments for the first quarter holds 19.5 percent of the smartphone market in the United States. This puts the device behind on RIM's BlackBerry in terms of market share.

As expected Jobs announced that the software development kit for the iPhone will be released next month. In the meantime, new software is being release for the iPhone in the form of firmware version 1.1.3.

New features coming to the iPhone immediately include Web Clips, an updated version of Google Maps that can automatically triangulate the user's location, song lyrics, the ability to send an SMS to multiple people, as well as a custom home screen.

Apple partnered with Google and Skyhook for the pseudo-GPS functionality. "I can flip right into directions, and it uses my current location to start," Jobs said.

Web Clips are essentially bookmarks that are stored on the home screen. Jobs showed how users can add new clips simply by clicking a button in Safari, much like how Web Clips work for Dashboard in Leopard. "I can create up to 9 home screens, and I can move between them with the flick of my finger," he said.

Applications for the iPhone will also go to the iPod touch, including Mail, Stocks, Notes and Weather. Maps will include the location feature when connected to a Wi-Fi network.

But there is a catch to this new functionality: existing iPod touch users must pay $20 for these features, while they come free with newly purchased players.
