Is it possible to unlock an AT&T Iphone 4s running ios 7.1.2?

Is this even possible? I have gotten as far as jailbreaking it and that is it. Then I installed Cydia app and from there installed ultrasn0w. What are my next steps, if it is possible to unlock it that is.

It is possible to unlock your iPhone. There are MANY tutorials online but, it is said that it is really easy to mess up and brick your iPhone and some methods aren't safe and what not. I wouldn't be able to tell you for sure what method to use since I haven't unlocked iPhones I've only jailbrocken them. Also, keep in mind that unlocking phones is now illegal (unless they lifted that law without me knowing) so proceed with your own discretion.

You can unlock your 4s all you have to do is take it to your carrier and see if they can unlock it for you
