Apple has just sent out invitations for an event being held on September 9 in Cupertino, CA, where the company is largely expected to reveal upcoming plans for its iPhone line.

As expected, the image sent along with the invitation doesn't reveal much of anything, aside from the tagline "Wish we could say more."

Even though Apple isn't hinting at much, it's more than likely that we'll see the next-generation iPhone—or iPhones—at the event. Speculation strongly suggests that the company will announce a pair of new smartphones, one with a 4.7-inch display and the other sporting a 5.5-inch screen.
