VPN on the iPhone

So I set up a VPN connection on one of our semi-public ASA devices. I tailored this connection to my iPhone.
The thought is that I could have remote access in case of disaster circumstances, and also give me, as the Admin, a little more flexibility to get my job done from anywhere.
It’s things like this that make me want to get an aircard or an iPad to get really remote- even the new Dell streak looks promising.
