Less than a week after launching iPad, Apple to show iPhone OS 4

Now that the iPad is no longer a mystery, Apple is sparking up its magic machine to get people talking and rumoring again.

In classic fashion, Apple has sent out invitations to an event it will be holding this week, which contain only a little detail but a lot of room for speculation and excitement.

So this Thursday, April 8th at 10:00am, Apple will give the world a "sneak peek of the next generation of iPhone OS software."
