I have seen a lot of people complain in forums that opening the battery cover on a Blackberry is difficult or even causes them to break a nail. Well, here is the solution: do not go straight for the fingernail-killer notch on the bottom center. Instead, gently lift the cover at the right and left edges beside the evil notch. The latches there will let go. Now go for the center notch and it’ll effortlessly snap off. If you were going in there to pull the battery for a reboot, consider installing the free QuickPull app to allow future reboots without opening the cover.
