iPhone Any recommendations for Sprint Factory Unlock Site?

[MacBOS]

I used Unlock Fusion before to factory unlock my wife's 4s, and then a friend approached me and asked for help doing the same on his phone. Only difference is that his is Sprint and my wife's is AT&T and wen i tried using Unlock Fusion i realized they only work on AT&T phones so I am wondering if anybody knows a equivalent service out there that can do the same for Sprint Phones and are just as reliable as Unlock Fusion is.

Thanks In advance

The only way to unlock a Sprint iphone 4S or iphone 5 is to contact sprint and have them unlock it.
And even then its only unlocked for international use and will work with GSM sims only outside the US.
It will not work with any other US carrier.
Yes, they are very restricted and nothing else you can do with Sprint iphones.
