So, to bring a little data to the table, two of the top 100 grossing US
iPhone apps are VPNs (Norton Secure VPN - WiFi Proxy, HotspotShield VPN &
Wifi Proxy).

I haven't used either one, but they are easily installed through the app
store and integrated into the iOS network settings app. These would bypass
any DNS-based filter policy.

You don't need to be hacker to install this stuff, and their position on
the grossing charts seems to indicated that they are effective (otherwise
people would not pay).

thanks,
Rob
