Websites/apps or anything for unlocking my at&t iphone 4?

I need to unlock my iphone 4 so i can use other service providers. I don't really care if it is paid or free as long as it is legit and gets the job done.

Do you have an active account with a carrier? Ask them you get you an unlock code. They should do it for free. T-Mobile has done this for me lots of times.
