The new operating system for iPhone and iPod touch brings peer networking, push notification, and access to external accessories At Apple’s Town Hall this morning, to a standing-room-only crowd of developers, Apple shared the details of iPhone 3.0. Highlights include peer-to-peer networking via Bluetooth, the ability for applications to use external accessories, and an open API for turn-by-turn navigation. Apple’s App Store will also have some new capabilities. Apple said the App Store will now allow users to subscribe to content. Developers will be able to publish add-ons to existing apps, such as new game levels or new cities for a travel guide, while users will be able to purchase and download these updates and extensions directly from within applications — no trip to the App Store necessary.[ For the full rundown on Apple’s new iPhone 3.0 OS, see InfoWorld’s special report ] Apple said that the new operating system features a new native SDK and more than 1,000 new APIs in all, many of which make easy and standard what many developers have already been doing for games. Other new features include support for e-mail within applications and streaming audio and video. Apple also shared a few measures of the iPhone’s and App Store’s success. In 2008, it seems 13.7 million iPhones were sold in 80 countries, while iPod Touch sales totaled 30 million units at year’s end. The App Store now contains more than 25,000 apps, which sparked 800 million downloads in the last eight months. As independent developer Steve Demeter put it, “Quit your boring day job, and get rich with the App Store.” Software Development
