iPhone 4s iOS 9 Release: 7 Important Details

iPhone 4s iOS 9 Release Date

The iOS 9 release date hasn't been rumored yet but thanks to credible iPhone 6s release date rumors, we know when the iPhone 4s iOS 9 release date might arrive. 

iPhone 6s release date rumors point to September 18th or September 25th in the United States. September 18th, at this point, is the best fit given Apple's history. 

Apple typically releases iOS 9 updates two days before it releases a new iPhone. So, odds are that Apple will release the iPhone 4s iOS 9 update on September 16th or September 23rd. September 16th is the safer bet right now. 

And remember, Apple releases all of its iOS 9 updates at the same time which means that the iPhone 4s will share a release date with the iPhone 6 iOS 9 update and so on.
