The oddly named Reestit Mutton site catalogs the cash-back and discount deals offered by UK mobile phone companies, figuring out all the angles -- follow their directions and assiduously apply for all the rebates and suchlike and you can get your phone and service for free (apparently in some cases, you can double-up on rebates and actually get paid to acquire a mobile and a year's service).

I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
