How to unlock/jailbreak the iphone 4?

I have a iphone 4 running on att&t that I have been using as a "ipod" and I would like to unlock it so I can use my carrier t-mobile and If you have any websites or youtube videos on how to do this it would be very helpful.

Here you go Bella!

Go to this website… It should answer all of your questions, and walk you through the process. Let me remind you to do this at your own risk, as it could possibly ruin your phone. Please be sure that you know what your doing, and most importantly… Have fun!

you don't need to go to a website or fill out anything.
