Is the value of the "battery pull" a myth?
So I've just upgraded my 9900 to 7.1.0.342, and of course I didn't hesitate to do a "battery pull", and will repeat a couple of times in the next few days to make sure my new OS "beds in" properly. But I find myself asking why on earth it should make a difference - either I should be pulling the battery frequently, whatever OS version I'm running, to clear out whatever's clogging up my BB, or it should just require one battery pull after loading the new OS.
Isn't the effectiveness of the battery pull just an old wives' (or old floppy-disk PC users') tale?
