Although the invitation to a press event has a 12 for the date I assume and a number 5 in the shadow, these were put together to mean iPhone 5 announced on September 12. But, a "leaked" picture of what looks to be a packaging printing machine now seems to show that the iPhone might just be referred to as iPhone with using the same naming as the new iPad... ie, "The new iPhone". The font, text, bolding and upper case letters are all in the right places when compared to the latest gen iPad, so perhaps this is correct.
In the grand scheme of things, it really isn't that important as all will finally be revealed next week. What would be funny is if Apple had planned all these fakes to throw everybody off the scent. Again, we'll know more beginning 6pm on September 12.
