We pretty much know that Sprint will be getting the new iPhone 5 which is expected to be announced this month and go on sale at the start of October, and now more evidence has appeared which point to a Sprint iPhone 5 launch, and it gives us an idea of the official iPhone 5 launch date.
Sprint has told its employees that they wont be able to take any vacations between the 30th of September and the 15th of October due to a ‘major phone’ launch.
Due to the possibility of a major phone launch in October we are blacking out September 30th through October 15th.
So when exactly will the Sprint iPhone 5 launch between those two dates, my money is on Saturday the 1st of October, which would mean that date would be the official Apple launch date as Sprint is expected to get it the same day as the other mobile carriers.
This would also tie in with the rumors that Apple will announce the iPhone 5 this month, possibly on the 19th or 26th of September, which would give them enough time to have the iPhone 5 available for pre-order before the 1st of October launch date.
