Welcome to the forums....
First, this is not a "hard reset". This is a "wipe handheld". As was already posted in this thread already it only erases user data. It leaves the OS and programs alone, just takes your data out of them.
Second, you cannot "wipe" the BES policy set on the BB if there is one. There is another procedure for that which is a little more difficult if you don't have a neutral one pushed from your company.
