If you already upgraded your Galaxy S3 to the latest I747UCALG1 ICS 4.0.4 (Ice Cream Sandwich) and wanted to root it so that you can make use a lot of your device by installing any apps you desired.
Well here's the easiest method, the best part of this rooting process is that - it will not trip the binary counter from the phone's security system. You would still be able to check for ota updates (although should just return the status of your software is up to date since it is a totally stock ROM just with root injected). Minimizing the hassles from resetting it once if you want to unroot it or completely return it back to its original factory firmware - for future use in-case in need of warranty.
I already mentioned this rooting guide from the previous ICS build I747UCALEM, which is a safest method to avoid the risk of losing the phone's IMEI number.
So, again this root method which already proven works on AT&T US version. The idea of this rooting technique is simply injecting a rooted kernel image from the official released ICS I747MVLALH1 firmware.
