I have an AT&T Blackberry 8310. I used to have a 8700g from T-Mobile. With the 8700g, I know there was a keyboard shortcut one could peruse in resetting the handheld much in the same way a hard reset would (without removing and re-inserting the battery). Is there such a shortcut that exists for the 8310, and if so, what is it? Thanks in advance to whoever responds.
