iOS 4.2.1 was released by Apple in November 2010. At that time, Facebook Messenger as a standalone app was barely a year old (launched in August 2011). The app was lightweight, simple, and worked over 3G and Wi-Fi.
Modern versions of Messenger (v250+) require iOS 11 or later. They use Metal graphics, AR stickers, and end-to-end encryption protocols that the old ARMv6/ARMv7 processors cannot handle.

For iOS 4.2.1, you absolutely should jailbreak (using redsn0w or Greenpois0n).
However, I can offer a structured outline and critical analysis that you could expand into a short paper or research note. This would focus on the security, legal, and technical implications of seeking legacy or modified IPAs.
While some archives exist that host old IPAs, there are specific hurdles for this version:
