Just when you thought the whole day was going to be about the iPad, Apple has gone and sent out invitations for a sneak preview of the iPhone 4.0 OS on 8 April. For those without a calendar to hand, that's just 3 days' time.

So far the rumours of the new features include being able to add contacts to the iPhone homepage as well as a global mail box view, but the one that's got folks talking is the addition of multitasking mooted to work in much the same way as Expose on the Mac platform.

Not long now to find out from the horse's mouth - once he's safely back in the stables, that is.
