Yeah, I remember people jailbreaking iOS 1 and installing various goodies. Then I remember getting an iPod Touch and a Mac Mini when (I think it was) iOS 2 came out add the SDK and app store so that I could try developing on their platform.
Well, it was technically going to be iPhone OS 1.2, but with the second beta, they changed it to 2.0. It didn’t become iOS until the iPhone 4 and version 4.0.
Sure... Also technically, I think they called it something different on the iPod Touch as well, if memory serves me right. :)
Yup, at the time, Steve Jobs was going full bore into web apps. He actually fought against having an app store for a bit.
