Which brings us to Lumia number four: the 610. As a budget phone currently going for free on a £15-per-month contract in the UK, it's been built on Nokia's belief that Windows Phone will run on almost anything: the merest of Snapdragon S1 processors (clocked at just 800MHz) coupled with a few crumbs of RAM (256MB).
