Apple has officially announced that the iPhone 5 will be unveiled at a special event on September 12. Using the date which casts a “5″ shadow as a teaser of sorts, a keynote address is planned for 10 a.m. Pacific. Suspected features include a thinner, taller iPhone with a 4-inch display – which abandons the 4:3 aspect ratio for one more like an HDTV. Rumors suggest Apple will start taking iPhone 5 pre-orders
