“ If you already have a web application, considering adoption of new WebKit technologies for CSS and HTML5. With animation and transformation available in Safari via CSS, impressive experiences can be delivered without ever needing to touch Objective-C. Similarly, HTML5 facilitates local storage in an SQLite database so that even if a user goes offline, he or she is never disconnected from your application. There are many examples of applications where more than this is complete overkill and over WiFi, the experience is certainly pleasurable. The iPhone SDK ships with Dashcode, a tool previously used to develop Dashboard Widgets but that now supports building full iPhone Web Applications using optimized native widgets. When possible, make use of it rather than hand designed images and CSS. Safari on the 2.0 OS goes further as well and supports gestures in the experience layer so that JavaScript can easily respond to pinching, swiping, and more.
