Actually your answer seems to support what mymitsu3kgt said. On the 8700 the notification for numerical lock is 'NUM' not '123'. And it never just pops up. It only appears when you press alt + num. If on your model it appears from time to time, it may be because of what mymitsu3kgt suggested, i.e. you are in a numerical field. If older Blackberries had this feature, it has been dropped on the 8700. (We still get numbers automatically entered in certain fields but no indicator that that is what will happen).
