[From Frank M] iPhone multitasking is on the way in iPhone 4.0 "The source said Apple will introduce "a few new ways" to run applications in the background, and a brand new syncing ability for contacts and calendars will be introduced.
It also stated, somewhat cryptically, "there will be multi-touch gestures OS-wide," and user interface and graphical changes aim to make the mobile operating system easier and more efficient to use. The tipster said the update would be made available only for the iPhone 3G and iPhone 3GS, leaving first-generation handset owners supposedly out of luck.
