Steve Jobs on third-party iPhone development: Write web apps

Steve Jobs' recommendation to developers seeking to produce applications for the iPhone: write Web applications.Declining to announce any actual SDK for the iPhone, Apple told developers at the WWDC today that they should write robust "Web 2.0 applications" for the iPhone, making use of AJAX and other technologies. These applications will all run within Safari, but can (with the right development) mimic the look and feel of already extant iPhone applications.The Web applications will have the capability -- like any other Web page in the iPhone's Safari browser -- to access iPhone functions like dialing a number, sending email, retrieving a map, finding contacts in Address Book and more.Disappointed? Relieved? .
