How to factory unlock iphone 5 and 4S?

So i got 2 iphones, one is locked to at&t network and other one to sprint. So i'm looking for ways to unlock them for free or low prices. I don't want to use any jailbreaking method as they don't provide permanent unlock, so i need factory unlock service. Any suggestions?

You can unlock them online.

The iphone on sprint is going to be expensive to factory unlock last i've seen its liek at least 79.99 to factory unlock the sprint version, and i'm not so sure even after a factory unlock sprint would work in the united states but should work over seas fine. The att iphone you can factory unlock for 20 bucks or so.

One site I highly recommend for their service is iphoneunlockedcheap.com They answered my emails promptly and the factory unlock was done in less than a day

EBay always best place to buy unlock code for iPhone. A lot of competitor make prices goes down

Buyer can always get money back if having any problem while unlock
