If you've been gripped by Olympics fever, we have a phone for you – the London 2012 Samsung Galaxy S III, which is available, as you might have guessed, for a limited time.Both the white and pebble blue version of the phone are available in an Olympics finish, the pebble blue with a Union Jack on the back, the white version with British Olympics imagery. Worried about looking a bit 'dated' once the event is over? Worry not, as Olympics sponsor Samsung is also throwing in an original back cover, so you can fall back in with the pack once we're over all the running, jumping, swimming, cycling and throwing.Aside from that, this is the same Galaxy S III we all know and love. Price-wise, Carphone Warehouse is offering the phone for free if you sign a £28 per month contract with Vodafone, Orange, O2, T-Mobile, Talk Mobile or Three. It will be on the market from 1 August. Just download the BBC Olympics app once you have it and you're sorted.
