Apple iPhone SDK Downloads Reach 100,000

The toolset is available at no charge and is being distributed first in the U.S.
Apple on Wednesday reported more than 100,000 downloads of the iPhone software development kit in the first four days following its launch last week.

Introduced March 6, the SDK provides developers with the same set of application programming interfaces and tools that Apple engineers use to create native applications for the smartphone and iPod Touch. Both use the same mobile version of Mac OS X.

"Developer reaction to the iPhone SDK has been incredible," Philip Schiller, senior VP for worldwide product marketing for Apple, said in a statement.

Schiller noted more than a million people had watched the launch video on the company site, a reflection of the "incredible interest developers have in creating applications for the iPhone."

Apple on Wednesday also previewed its new App Store, which will be the only way independent software developers will be able to distribute their work to iPhone users. Developers can set their own price, but Apple gets 30% of sales revenues. Corporate developers will be able to build their own custom apps and distribute them only to company employees.

During the SDK launch at Apple headquarters in Cupertino, Calif., Apple partners AOL, Electronic Arts, Epocrates,, and Sega demonstrated applications they built in two weeks with the toolset.

Apple trotted out a number of other companies working on iPhone applications, including personal financial software maker Intuit, online business software provider NetSuite, game developers Namco Networks, PopCap, and THQ Wireless, and messaging software maker Rocket Mobile.

The SDK is available in beta through Apple's developer Web site. The toolset is available at no charge and is being distributed first in the United States. The developer program will be expanded to other countries later this year.

In June, Apple plans to distribute version 2.0 of the iPhone OS, which will be available to users at no charge. The upgrade will include support for applications built with the SDK. Apple also plans to make available at the same time for a "nominal fee" a similar upgrade for the iPod Touch.
