iOS 2, the early version of Apple's mobile operating system, was originally released on July 11, 2008, alongside the iPhone 3G. It was a significant update as it introduced the App Store and several new features such as support for Microsoft Exchange, parental controls, and various improvements in the Mail app. If the question is about iOS 18.2, the next iteration in the future, it is expected to be released in December 2024, likely around the first half of the month. If the question refers to the latest version iOS 26, it is scheduled for release on September 15, 2025.
