BLACKBERRY 9360 UNLOCKED USED BUT IT GOOD CONDITION PHONE CHARGER AND ORIGINAL BOX BUT SMALL PROBLEM *

HI I HAVE A FULLY WORKING BLACKBERRY 9360 UNLOCKED HOWEVER THERE IS A SLIGHT PROBLEM. THE BUTTON ABOVE THE SCREEN DOESNT RESPOND. PLEASE NOTE THIS DOESNT AFFECT THE PHONE AT ALL, SO BASICALLY THE PHONE IS STILL FULLY OPERATIONAL. THIS IS WHY I AM ASKING FOR A LOWER £100 PRICE FOR THIS PHONE THANKS
