"We’ve independently heard that Apple has plans to begin selling the next-generation iPhone on Friday, October 7th; the date first reported by TiPB. According to our sources, Apple has been weighing between launching the new iPhone on October 7th or October 14th, but with the product’s latest stages of pre-mass-production currently moving along nicely, Apple is presently shooting towards a launch on the 7th. On top of this, unlike with the iPad 2, Apple plans to offer pre-orders for the new iPhone."
