Tor (the onion router) works on jail-broken ios 3.2 - 4. I think this is pretty important. First real browsing anonymous tweak, doesn't slow it down very much either. Totally awesome. http://sid77.slackware.it/iphone/howto/ installing the .deb file there puts the repo you need into cydia install mobile tor adjust your proxy settings for your wireless network Settings -> WiFi -> Your Wireless Network ESSID -> HTTP Proxy Manual and set Server as "127.0.0.1", Port as "8118", leave Authentication "OFF": iPhone OS SHOULD transparently proxying any traffic through the Tor network now. might be old news but i searched tor and nothing came up so don't give me any flack about it. also, there is an sbsettings toggle.
