It’s been awhile since we’ve had any juicy iPhone OS update rumors to chew on, but today brings a small feast of them.

Boy Genius Report is reporting that one of their “trusty Apple connects” named Lindsey has come forth with some details on iPhone OS 4.0 features which everyone at Apple  is “really excited” about, complete with the screenshot you see here as evidence. As always, take these kind of things with a grain of salt, but if true, looks like some nice stuff could be on the way.

First up, multi-touch gestures will now be supported across the entire OS, which BGR claims is necessary as part of the forthcoming iTablet -- and yes, they claim that is the actual name that Apple is going to run with.

Also on deck are “a few new ways” to run applications in the background, which probably means multitasking will finally catch up to the Android and WebOS competition. There are a number of “graphical and UI changes to make navigating through the OS easier and more efficient” -- no details on what that means, but like BGR, we hope that means improved notifications and maybe a refreshed home screen, at least.

There’s a “vague” detail about a new syncing ability for contacts and calendar applications -- we can only hope that perhaps Wi-Fi syncing will finally be a reality, and if it extended to iTunes media syncing, all the better.

Finally, word on the street is that iPhone OS 4.0 will abandon support for the original 2007 iPhone -- it will only work on the iPhone 3G and 3GS. The good news is, the new OS update will “put them ahead in the smartphone market because it will make them more like full-fledged computers.” Probably not going to make those of you holding onto your 2G iPhones happy, but as always, technology marches on.

We’re ready for next Wednesday, how about you?

(Oh, and before anyone tries to debunk this tidbit by noting that the above screenshot simply says “iPhone” at the top, let’s remember that space actually shows the name you assign your device, not the model of device you have. It automatically defaults to “iPhone” regardless of which model you have. If you don’t believe us, go ahead and look for yourself. We’ll wait.)
