True to the spirit of the Apple iPhone rumour game, information about the iOS 4.0 has already leaked.

Boy Genius Report has picked up some tasty morsels on the new operating system, giving yet more hints that there's a new iTablet in the works.

The new iOS 4.0 will offer more universal multi-touch gestures, which we're widely expecting for the new iTablet when it's (likely) announced at the end of the month.

There will also be some UI improvements, although we doubt this will be anything earth shattering, as Apple has always preferred simplicity and continuity in its iPhone design - we'd imagine something like a swipe upwards to offer speedier access to certain elements of the iPhone (in the same way as Spotlight search).

Apparently there will also be some new changes to let multiple applications run at once - but again, we find it hard to believe Apple will offer genuine multi-tasking on the iOS 4.0, instead we'd imagine it's just key applications that can run together.

Super computers

And interestingly, the source states the iPhone 3G and iPhone 3GS will also be taking advantage of the upgrade, stating it will "put them ahead in the smartphone market because it will make them more like full-fledged computers".

This must mean some pretty decent extra functionality as well as some hardcore hardware optimisation - seeing as the 3G is looking pretty dated, with it being nearly two years old.

Anyway, we're looking forward to finding out about the new iOS 4.0, which we're anticipating being launched on 27 January.
