iPhone 5 and iPad Mini to be Announced on September 12th with iPhone 5 Release September 21st
iMore reports that they have heard that the next generation iPhone, new iPod nano, and all new 7.85" iPad mini will be announced on September 12th. They also pinpoint the actual launch date for the next iPhone as September 21, 2012.
iMore has heard that Apple is planning to debut the new iPhone at a special event on Wednesday, September 12, 2012, with the release date to follow 9 days later on Friday, September 21. This information comes from sources who have proven accurate in the past.The next-generation iPhone, which is frequently referred to as the "iPhone 5", is expected to have a taller 4" screen as shown in the above photo. Rumors have also suggested the inclusion of high speed LTE wireless networking.
While we generally refer to the next iPhone as the "iPhone 5", if Apple follows the example of their most recent iPad release, they may drop the numbering scheme with every new iPhone release. The 3rd generation iPad was simply called "the new iPad" in all press materials. Similarly, it seems likely that Apple will simply refer to the next iPhone as "the new iPhone".
While the 7.85" iPad mini has been long rumored, there has been a notable increase in the frequency and volume of rumors related to the product. The smaller iPad is believed to help Apple fill a cheaper price point in their tablet lineup.
iMore has been an accurate source of release date information in the past. They previously pinpointed the iPad 3 launch date as well as pre-order date for the iPhone 4S.
