You can't operate a BlackBerry without a battery. I tried, hoping to be able to swap batteries while on the wall charger to avoid the long reboot time. It won't work. The phone reboots anyway. Apparently the BlackBerry draws too much current in normal operation for the wall charger to power it without the battery.
I guess it never occurred to you that one might find oneself with a blackberry that might or might not work and one doesn't want to add to one's collection of useless objects by getting a new battery only to find out that the blackberry's problem was not the problem but rather it was the blackberry itself. Given that you didn't think of this, perhaps you should rethink your qualification to make off-hand comments.
