Firmware expected sometime in summer
A YouTube video posted by the Polish site MakoweABC shows the iPhone OS 4.0 beta, including the new multitasking features and folder creation. The host demonstrates how to launch several apps and bring up the multitasking toolbar with a double press of the home button. Each of the app icons are listed on the bottom of the screen, allowing users to terminate each app by tapping and holding on the icon.
To create a folder from two game apps, the host taps and holds one of the icons to move it on the screen. Instead of rearranging the icons, the app is placed atop another icon to create a folder which can then be renamed.
The iPhone 4.0 firmware is expected to be available for the iPhone and iPod touch sometime in the summer, although the multitasking functionality will be restricted to the iPhone 3GS and third-generation Touch.
