Hot on the hells of the iPad launch, Apple is continuing fell speed ahead, as they’ve invited a select group of media to come get a look at the unveiling of iPhone OS 4.0. As you can see in the image, the invite has a shadow of a large number “4” figure, and invites us to “Get a sneak peek into the future of iPhone OS.” The event takes place at the Cupertino campus, it’s just 3 days away, and we are excited.
