Many vintage BlackBerry phones will stop working on Tuesday as the company turns off support for its operating system. Launched in 2013, that particular model, and BlackBerry's phones since then, have faced an increasingly impossible battle as Apple and Samsung set about their battle for global smartphone domination. Announcing the termination, BlackBerry thanked "our many loyal customers and partners over the years". It means remaining die-hard owners of their devices won't be able to make or receive calls, send texts, use wi-fi or access mobile data. It is almost exactly 23 years since BlackBerry launched its 850 phone, and the company soon became the leader in providing emails when out and about on the move. But the models that followed the iconic BlackBerry Bold would face increasing competition from Apple and Android phones.
