- Jailbreaking/Legacy Devices: They have an old iPhone 4 or iPhone 3GS stuck on an old iOS version (like iOS 6 or 7) and want to run WhatsApp on it.

Background and context
- WhatsApp 2.3.6 refers to a very old release series from the early era of WhatsApp on mobile platforms. On iOS, WhatsApp has had many major revisions since the app moved from simple messaging to a full-featured service (voice, media, encryption, status, Business, etc.).
- Old versions like 2.3.6 were released before major privacy, security, and platform changes (e.g., wide adoption of end-to-end encryption, iOS API changes, and modern app signing/entitlement requirements).
