Just 48 hours after launch, the full featured new iPhone model sold out its inventory and Apple merely promised buyers of the phone that they would receive their device in "October". Following that, Apple listed a 2-3 week lead time until the just posted reduction to 1-2 weeks.
Meanwhile, the plastic-coated Apple iPhone 5c has always been available for transit in just 24 hours after ordering. There are some contradictions about how well the iPhone 5c is selling. A couple of reports say that Apple has cut orders to Pegatron for deliveries of the device while another report says that Apple is adding suppliers for the phone.
Apple wants to have the new iPhone models available in 100 countries by the end of the year, a figure that is now up to 60.
