Samsung Galaxy S II

The Samsung Galaxy S II is the phone the Korean firm deems the successor to its best smartphone so far. And with a 1.2GHz processor, super-slim chassis and feather-light innards, it's easy to see why.
The dual-core race is set to heat up massively over the next few months, with the LG Optimus 2X already released, and the Motorola Atrix, HTC Sensation and iPhone 5 all set to bring the tech to market too.
Coming in at £35 a month and £519.99 SIM-free, the Galaxy S 2 isn't the cheapest phone out there by a long chalk – so let's see if it can match up to that larger price tag.
