Apparently, demand for the new iPhone 6 models have exceeded the initial pre-order supply, and this has caused a number of iPhone 6 pre-orders to be delivered in October instead of this month. Apple has more or less anticipated this to happen, and will be sending over additional supply of iPhone 6 and iPhone 6 Plus devices to walk-in customers this coming Friday, September 19, at 8:00 a.m. local time at Apple retail stores.
This Friday will see both models made available from AT&T, Sprint, T-Mobile, Verizon Wireless, while other carriers and select Apple Authorized Resellers too, will be able to offer the new iPhones. I suppose it is all right not to be an early adopter, as you will eventually be able to lay your hands on the iPhone 6 after the initial frenzy has died down. [Press Release]
