I don't recommend ever using that address. First of all, it isn't an address you can control. When you switch carriers, it is gone forever. If (and when) RIM goes down, you have no email via that address as it can only be accessed on the BB. Next, there is no SPAM filter on it so if it ever gets out in the free and clear, you are liable to get tons and tons of SPAM. And finally, there is always the issue of ensuring you are replying via the correct reply to address.
