Hi all. I'm a first time BB owner and i'm trying to get used to this thing. I just bought a used 7290 from someone. It was from some company who got rid of them to upgrade(cinguar carrier), and i have a problem. It times out i guess you could say, forcing me to enter my password, pretty much whenever i set it down. It's roughly 2 minutes before it locks itself again. This is very inconvenient and i tried to adjust it for a longer time, but it has no effect. Also, i tried to disable the feature in options and security setting, and it will not allow me to change it, it doesn't even give me the option to do so. It only has enable, not disable. Any help here or am i screwed?
