I have a 2 week old Galaxy Ace, in Plum Purple, SIM FREE, with a 2GB and 16GB Micro Sim, official Samsung Leather case, and car mount which I would swap for a 3GS, colour and RAM irrelevant so long as it is in nice condition and will work on Three.
Will chuck in an iPod Nano (3rd Gen I think - the rectangular one) 8GB too with Apple Headphones and sync cable.
