iPhone OS 4.0 to arrive 1/27 with new interface, multitasking?

Our pals over at Boy Genius Report are saying they’ve received some inside information about the iPhone OS 4.0, which is heavily rumored to debut, and possibly even be released, at the Apple event on January 27th. Here’s what they are saying about iPhone OS 4.0:

• There will be multi-touch gestures OS-wide. (Would make sense for that as the rumored OS for the iTablet is close if not the same as the iPhone)
• “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. We haven’t had this broken down, but we can only hope for improved notifications, a refreshed homescreen, etc.
• 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.

As far as we’re concerned, we think that a graphical and UI interface refresh is definitely needed for the iPhone, which hasn’t really seen any major interface changes since it launched. Of course, we will be bringing you all the new on January 27th as it happens.
