Finally, it's official. Apple has sent out invitations to an event on September 12. It'll be held at 10 a.m. Pacific and 1 p.m. Eastern time at the Yerba Buena Center for the Arts Theater in San Francisco. As usual, the invitation is cryptic and doesn't say what will be announced. And as usual, enthusiasts are scrutinizing it for hints, since Apple often does give a few clues. The invitation has a large numeral 12 indicating the date, but casting a shadow of the numeral 5. Which apparently indicates the iPhone 5. The text simply reads "It's almost here." The event will also likely announce when iOS 6 will be available, which many are looking forward to.
