According to a report of AllThingsD, Apple is preparing for the upcoming event to be held on October 4. Report also suggest that new CEO, Tim Cook will be the keynote presenter and will be accompanied by other executives who will take part in the presentation, as has been done in the past on the side of Steve Jobs.
The site says that availability of the device is within a few weeks from the date of the notice. Obviously, The date may be subject to change at the last moment (and as always, Apple will issue invitations to the press just days before the conference for this reason) but it is very likely that we will see iPhone 5 on shelves with in two weeks after the official announcement.
