Apple has surprise iPhone 4.0 preview
Apple today surprised the media by sending out a teaser for an iPhone 4.0 event at its Cupertino campus on Thursday. The event notice says little but offers a "peek into the feature of iPhone OS" with a large "4" casting a shadow, clearly pointing to the next major revision.
Although Apple has said nothing about 4.0, most expect it to center on Expose-style multitasking that involves a double-tap of the home button. It may also bring a generalized file system that lets users save and open documents from outside of a particular app and should roll in many of the iPhone 3.2 developments seen with the iPad, such as a home screen with a custom background and icons that rotate regardless of context.
