Να τι τους είπε η ''έμπιστη'' πηγή τους:

•  There will be multi-touch gestures OS-wide.
•  “A few new ways” to run applications in the background — multitasking.
•  Many graphical and UI changes to make navigating through the OS easier and more efficient.
• The update will supposedly be available for only the iPhone 3G and 3GS, but will “put them ahead in the smartphone market because it will make them more like full-fledged computers” more than any other phone to date. Everyone is “really excited.”
• The last piece of information is the most vague, but apparently there will be some brand new syncing ability for the contacts and calendar applications.

The iPhone OS 4.0 firmware is expected to be announced at Apple’s special event on January 27th.
