Along with multitasking for background apps, iPhone OS 4.0 will allegedly include system-wide multi-touch support, OS interface improvements that make navigation easier, and improved contacts and calendar syncing. Apparently the 4.0 update will be compatible with the iPhone 3G and iPhone 3GS, but not the original iPhone model.
Boy Genius Reports claimed the information came from a reliable connection at Apple, but until the company reveals exactly what’s in store for iPhone OS 4.0 this information should be treated as nothing more than another pre-media event rumor.
