Apple concurrently provides the same version of iOS for the comparable model of iPod and iPhone, usually devices released in the same calendar year. iPhone users receive all software updates for free, while iPod touch users paid for the 2.0 and 3.0 major software updates. As of iOS 4.0, Apple no longer charges for iPod touch updates.

Unreleased versions

As of October 23, 2011 two versions of iOS were never released: iOS 1.2, that after the first beta was replaced by 2.0. (the second beta was called 2.0b1 instead of 1.2b2). The other release was iOS 4.2, that was replaced with 4.2.1, because of a Wi-Fi bug in 4.2 beta 3, which caused Apple to release 2 more Golden masters (4.2 GM and 4.2.1 GM).
