To hide your ip you need to do a couple of things
Use a elite proxy
use a vpn with socks4/socks 5 support

Use only the elite proxys. Easy way to import them is to use Charon or proxy switcher pro which will import them automatically for you.
Then there's services like jondo and your-freedom. Both offer free vpn and tunneling services but their god Damn slow. Your-freedom can tunnel a way onto the internet from mars if it has to that's the power of it.

Loki vpn and cyber ghost are also good ones you can look at. If your thinking about using cyber ghost let me know I got a years free subscription lying around somewhere that I have no use or need for.
Then there's Tor and gpass. Gpass also quick and easy to use and you can use it with Tor aswell. Tor is one of the best but you have to give it a couple of min to speed up. Use it with the tor browser aswell coz its where it can be the difference between you staying anon or your being seen by your real ip. DO NOT USE OPERA WITH ANY PRIVACY PROGRAM. It doesn't support socks which leads to dns leaks showing your real ip.
Use tor-> modded firefox tor browser or
I prefer jondofox as its firefox with all the privacy add ons pre installed and add block plus, no script etc etc are already installed aswell. Basically it runs of your current firefox but just with the jondoprofile.
