Release notes

Overview

Editorial synthesis with inline references and a source ledger when citations are available.

A contemporaneous MacRumors report dates the iPhone 2.2.1 release to January 27, 2009 and preserves two items from its update notice: a general Safari stability improvement and a correction for some Mail-saved images failing to display properly in Camera Roll.[1]

The report also notes a contemporaneous iPod touch package, but this batch targets only the existing iOS public route. Apple’s archived security index contains no separate 2.2.1 entry, so no security fix or build number is inferred.[2][3]
