[UPDATED 12/30/2012][Sprint Only]UnRoot and Return to stock
If you are unrooting to take your phone to Sprint, you will want to clear your flash counts first. If this is not required you can skip this step.
“ DO NOT FOLLOW THIS PROCEDURE IF YOUR PHONE HAS RECEIVED THE OFFICIAL UPDATE TO ANDROID 4.3. ATTEMPTING THIS PROCEDURE WITH A PHONE WHICH HAS BEEN UPDATED TO ANDROID 4.3 WILL PROBABLY HARD BRICK YOUR PHONE.
This procedure is intended only for Sprint Galaxy S3 devices running Android 4.1.2 or earlier.
Always check your current count state in download mode prior to using triangle away. If what Triangle Away and what is shown in download mode doesn't match, do not proceed.
You will be will be resetting your phone with an app called triangle away, which has just been updated to support all US versions of the GS3. Click on the link below to download triangle away.

Installation instructions and how to use it are in QBKING77's Video Below.
Here's a one file one flash method to return to stock. This will return you phone to a stock unrooted state. While you will need your drivers and Odin desktop loaded, you will only be flashing a single file to your phone.
This Has Been Updated on Dec. 30, 2012. The new Return to Stock file will fix many of the issues that were present with the old file. It will no longer wipe your data or set up. It should also fix the issue with hanging on the Samsung screen. If you are currently on ICS this method will also update you to the current LJ7 Jellybean without wiping your data.
Your Samsung Drivers MUST be installed correctly on your computer prior to continuing.
Wait until the software installs completely before plugging your device into the computer. When you have completed driver installation, plug in your device. The computer should now tell you it is installing drivers, click on the details and wait until there is a green check by all the drivers. Unplugging your device before it's complete will cause you problems...
Attention Windows 8 Users: The drivers below are updated to work on Windows 8. If you have upgraded to Windows 8, installed these drivers and they still won't work, you will have to install the drivers in compatibility mode.
Download and install on your computer.
Preparing Your Computer
You will need to download the following files to your desktop or notebook computer. Just
click on the file names and that should download the file required. I would suggest you
make a folder on your desktop and name it something like Root GS3
Return to Stock JellyBean
After downloading the above files to your computer:
1. double click on the "Odin 3.07 zip". Copy the "Odin307" folder into your "UnRoot GS3"
Double Click on "Samsung-Updates.com-SPH-L710_SPR_1_20121019105628_mflxsj3ffx.zip" And Copy
files to the UnRoot GS3 folder. In other words, extract the tar.md5 file
from the zip and copy it to the UnRoot GS3 folder.
1. Open the "Odin307" folder and right click on "Odin3 v3.07.exe" and choose run as administrator. Odin will open.
2. place your phone into download mode. Turn off phone - press and hold volume down, home button and power button at the same time. When you see the warning push the volume up button to continue.
3. Plug your usb cord to your phone and computer and wait until you see any number and com in the ID com block.
4. Check the PDA block and click on the pda button to browse to
"KIES_HOME_L710VPBLJ7_L710SPRBLJ7_329968_REV03_user_low_ship.tar.md5" in your UnRoot GS3 Folder
5. Verify Auto Reboot is checked as well as F. Reset Time
When all this is setup Odin should look like this:
6. If everything looks like the picture, click on the start button in Odin.
Note: This is vary large file and make take up to 10 minutes to complete.
If your phone sticks on the samsung screen for more than 5 minutes, boot into stock recovery and perform wipe/factory reset. Then restart your phone. First boot normally takes longer, so please be patient.
When the phone leaves download mod and starts to reboot you can remove the usb cord.

My method is nothing more than the original firmware that came on your phone and installed by samsung. All you're doing is flashing it back with Odin. If you want to reset it completely and remove all your apps and data as well. It can be done as well but since most people would like to save that, I didn't include the steps to do so.
You can also install ota root keeper from the market. It will temporarily disable root which used to work well to get ota updates but the manufacturers and carriers are getting smarter and look for stock recovery as well, so it just keeps getting harder to fool them.
If you are on a custom Rom it will most likely be getting the update soon if not already. So you can wait and flash the upgraded Rom.
Just Flash It !!!
You can gtalk with me if you want help. I will pm my gtalk contact info.
Just Flash It !!!
