Blackberry Bold 9000 unlocked to any network with Faulty Trackball .

Hello I am selling my blackberry bold 9000 which is unlocked to any network. It is in good condition apart from the trackball. You can press, roll it down-up, and left but no right. I have no clue what could be the reason. It may be trackball itself or the house of trackball. So if you know what you are doing, it could be so easy to fix. As an addition I will incluede dock charger which I had paid 15 pound. It makes it so stylish indeed:) I am looking for 55 or without dock 45. UK ONLY! Thanks for looking Please text me on 07447900944
