SONY ERICSSON MIX WALKMAN PHONE ?

I HAVE ONLY HAD THIS PHONE SINCE LAST XMAS SO STILL HAS SOME WARRANTY LEFT. I CANT GET USED TO IT SINCE I HAVE ALWAYS HAD AN HTC PHONE SO AM SELLING. IT STILL HAS THE BOX AND IS AS GOOD AS NEW CONDITION. HOPING FOR IT TO GO TO SOMEONE WHO LIKES THE SONY ERICSSON MODELS. IT WAS BOUGHT FROM TESCO BUT I BOUGHT A CODE OFF THEM SO IT CAN BE USED ON ANY NETWORK. THANKS FOR LOOKING. RETAILS
