Apple has announced their September 12 special event, expected to see the introduction of the next generation iPhone 5. The information on the invitation is sparse. According to the graphic shared by Jim Dalrymple of The Loop, it shows the number 12 (the date of the event), and the number 5 (make of that what you will), along with the following line: "It's almost here". According to Jim:
The invitation I received says the event will take place at the Yerba Buena Center for the Arts at 10:00 am.
iMore posted the September 12 Apple event date back on July 30, along with what we believe to be the U.S. launch date of September 21. Back on August 13 we posted what we believe is the second wave launch date of October 5.
