They ran Windows Mobile 6.1—an operating system that felt like shrinking a desktop PC down to a 3-inch screen. It had styluses, resistive touchscreens that required a fingernail or a poke, and a browser that tried its best to render HTML.
The biggest hurdle for anyone finding an old WhatsApp CAB today is the digital certificate. Every CAB file is digitally signed. Most of those certificates expired years ago.
