4. The "Facebook" App vs. "Messenger" App

• Before 2014, messaging was integrated into the main Facebook app.
• A legacy Facebook app IPA (circa 2011-2012) might technically install on iOS 4.2.1 if found.
• However, the standalone Messenger app was not introduced until later and required iOS 5 or 6 for its earliest versions. Therefore, a "Messenger IPA for iOS 4.2.1" likely does not exist as a standalone file that was ever officially supported on that specific firmware version at launch.

To install a downloaded .ipa file (like those from the Internet Archive), your device must be jailbroken. Note: iOS 4
