The iPod touch launched 2 months after the original iPhone launched, and they both ran iPhone OS. Why are you so stubborn over something that can be easily searched and debunked?

iPhone OS existed until iPhone OS 3.2.2 when it was renamed to iOS in iOS 4. https://en.wikipedia.org/wiki/IOS_version_history

IOS (and iPhone) were trademarks owned by Cisco so Apple had to license them. As far as I remember for iPhone they just released it and then bargained using the exclusive vpn client being Cisco’s. I don’t know what they gave for iOS.
