Blackberry bold 9900 CHEAP -

hey guys blackberry bold 9900 for sale no pics but its in a good condition everything worked beforehand but when i put the battery in and it will load up then reboot itself which it keeps on doing im not an expert so it might be a n easy fix but i dont know i want 150 for it comes with battery 490 in shops so this is a bargain might be an easy fix not too sure as im not an expert eevrything was working before the touchscreen etc
