The original iOS 2 (then called iPhone OS 2) was released on July 11, 2008, alongside the iPhone 3G. However, if the question refers to iOS 26, the latest version, it was officially released on September 15, 2025, around 10:00 a.m. Pacific Time globally. This is the most recent major iOS release with a new design and features, available for iPhone 11 and later models.
Could you please specify if you meant iOS 2 from 2008 or the latest available iOS, which is iOS 26 in 2025?
