iPhone OS 4.0 announced: Multitasking and more!

The new OS will ship in June (Fall for iPad, and a developer preview is available today) and has the following new or updated features:
• Multitasking
• Fast app switching
• Local notifications
• App folders
• A new Mail app
• iBooks
• Custom backgrounds
• Game Center
• iAd advertising
• 5x digital zoom
• Bluetooth keyboards

When the software ships in the summer, iPhone 3GSes and iPod Touch 3rd-gens devices will get all of the new features. The iPhone 3G and Touch 2G will get “many things,” which doesn’t include multitasking. I repeat: the iPhone 3G won’t get multitasking, ever. iPhone 2Gs will be left on a hillside somewhere to die of exposure, or something.
