The software running those Nokia phones of yore is actually based on a simpler version of the Symbian operating system, Symbian S40. The basic grid interface will be familiar to anyone who’s used a Nokia phone – 3G or not – anytime since the 90s, and in fact, other manufacturers such as Sony Ericsson (now simply known as Sony) and Samsung use the same Symbian base for their phones.

Nokia isn’t tied to a single operating system though – the Finnish manufacturer announced last year its alliance with Microsoft to make Windows Phone smartphones, while word is that it is looking at the Linux-based Meltemi for its feature phones.
