Nokia 5110 (1998)

 

One of the many Nokia models that became near-ubiquitous in British universities, high streets and offices, the 5110 was nigh-on impervious to anything the world could throw at it, had excellent battery life and, of course, came with the beloved Snake on board. You could also pop off the front panel and swap it with one of several bright-coloured replacements because, well, customisation.
