Please note; this requires you to jailbreak your device. You can install a iOS 7 jailbreak from http://www.evasi0n.com Jail breaking takes less than five minuets and if you don't like it, just restore your device via iTunes. Not hard at all. For security reasons, you must be connected to wifi for this.
If you already are jail broken, open Cydia and search for Tor. It should be the package that shows up, install it. Once you are finished, go to Settings>Tor Settings and enable Tor.
Once it is enabled, go to your wireless settings and you will see three panels. go to your wireless settings and select your Wireless network, under the settings you'll see three panels: Off, Manual and Auto. you will need to select Auto and punch in: file:///etc/tor/proxy.pac after that, you are set-up to use tor, launch Safari or Google Chrome and give it a spin.
Congrats, as long as tor is enabled all of your internet data going through your phone is through tor.
If you'd like to confirm it's working, go on http://ipchicken.com
Or you could just download Onionbrowser from the appstore and skip all this bullshit.
