In case you were wondering whether to go go for the HTC One X over the newly announced Galaxy S III, then here’s your push in the HTC direction. Phones4U has an extremely good offer on Vodafone over a 12 month contract. The premium was originally £149.99 but this has been reduced to free. This package will give you 300 minutes, unlimited texts and 500MB of data. When you add this up it comes out at £432 which is cheaper than buying SIM free. There is no guarantee that you will get an unlocked phone though, but Phones 4U is a massive bulk buyer and tends to buy direct from the manufacturer and not the network.
