Vodafone 360 H1 £429.99 Sim-free
This phone is by Samsung and it runs on the LiMo operating system. The phone features a 3.5-inch touchscreen and it isn't the most responsive of devices. But it is centred around social networking as it integrates your Instant Message chats, Facebook updates, and Tweets all into a visual address book. Other than that - its just another run of the mill phone.
