The upcoming iPhone OS 4.0 will deliver support for multi-tasking using a expose-like interface, according to AppleInsider.
Those familiar with the design of iPhone 4.0 said that the user interface will resemble Apple’s desktop Expose feature, in that a key combination — reportedly hitting the Home button twice — will trigger an expose-like interface that brings up a series of icons representing the currently running apps, allowing users to quickly select the one they want to switch to directly. When a selection is made, the iPhone OS zooms out of the Expose task manager and transitions to that app.
Other notable features of the iPhone 4.0 firmware are a global mailbox view and the ability to add individual contacts to the home screen.
