WhatsApp actually began its journey during the transition between the old-school stylus-driven OS and the modern touch era. While WhatsApp became famous on iOS and Android, there was a brief window where "cross-platform" included Windows Mobile.
However, there is a common point of confusion: WhatsApp never officially released a stable version for Windows Mobile 6.1.
Windows Phone vs. Windows Mobile: WhatsApp was heavily developed for Windows Phone 7.5, 8, and 10. These OS versions are entirely different from the kernel used in Windows Mobile 6.1/6.5.
The "Homebrew" Scene: In the heyday of XDA-Developers, many coders attempted to port apps or create wrappers.

IRC Clients: Internet Relay Chat is one of the few protocols that still works on vintage hardware. You can find legacy .cab files for "PocketIRC" to stay connected.
Telegram Lite (Unfinished Ports): There were very early attempts to bring Telegram to older hardware, though these are also largely non-functional now.
SMS Syncing: Many collectors use their HTC devices purely for SMS, using the physical QWERTY keyboards of the HTC Touch Pro series for a tactile texting experience. Final Verdict
