Good news everyone!
If you have a Sprint iPhone 4s on iOS 7.x and you want to use a Gevey Ultra S (v2.02) to get your phone unlocked. I have found a way to do it!!!!! HAHAHAHAHAaaaa!!!!!!
Just follow these steps and it will make all your dreams come true. Please note, I did this using and iPhone 4s that is locked to USA carrier Sprint (CDMA) running iOS 7.0.6, and I was using a T-Mobile USA SIM card:
1) Make sure your Gevey Ultra S is programmed to USA Sprint carrier. This web page explains how to do this:

2) Restore you iPhone to 7.0.6 using iTunes. If a newer version of the iOS is out I can not guarantee this will work.
3) Use evasi0n7 to jailbreak your iPhone 4s. This web page explains how to do this:

4) Add the source
http://cydia.furiousmod.com/ to Cydia. Look for the section labelled "Manually Adding a Source to Cydia" on this web page for instructions on how to do this:

5) Install FuriousMod for iPhone 4S CDMA iOS 5.1.1. You can find this by clicking "FuriousMod.com" in the "Sources" section of Cydia or by searching for it.
6) After it's installed you'll need to restart you iPhone. Make sure the Gevey is in your phone with the SIM card for T-Mobile (this might work with other card types but I only had a T-Mobile card to test with).
7) When your phone starts up is will say "Your iPhone was unlocked successfully by GEVEY". This is a freaking lie! Don't believe them! At the bottom of this message there will be an activation code or something like that. Mine was 6 numbers. Quickly write this number down on something.
8) Now run the FuriousMod4S app on your phone.
9) Enter the code you wrote down and your done.
Please note: You may have to restart your phone again and it might tell you that there's an update to the carrier settings CANCEL THAT *****!!!!
And there you have it folks, a unlocked, jailbroken, Sprint iPhone 4S with 3G, data, text, calls and everything else you'd ever want.... I think... I really only tested calls, data and texts. Sorry, I'm really drunk.
