Since it does not have an ctrl-alt-del option, I was left with no other option than to hard-boot it (literally!). So I took out the battery and replaced it after a few seconds. It took the BB a few minutes before it completely booted on but that seemed to have done the trick. It has been running smoothly since yesterday and the charge is still over 90%.
hold alt + right shift + delete on qwerty devices to reboot.
