Well folks, that day has come as the XDA developer by the name of AdamOutler has released instructions on how to unlock your Verizon Galaxy S III’s bootloader. Before I give you all the instructions, it’s important to first read AdamOutler’s precautionary statement first:
Let me make this clear. If Samsung updates your device’s bootloaders, using this tool could potentially brick your device. Once you apply this, never accept a factory update without first flashing the Odin Packages in the Original Post of this thread. As a general rule, you want to be the last guy to apply any Samsung update. Run custom.
As of the date of this posting, this works great on Linux and it should work wonderfully on Mac too. If you’re using Windows, I recommend downloading Windows Ubuntu Installer(WUBI) to install Ubuntu from within Windows.

Please keep in mind the risk you’re taking if you decide to try this. If you’re not comfortable with the steps shown, then I highly suggest to not attempt it. This is still a new process and in my personal opinion, I would at least wait a couple of days before trying this and see how other people’s experience with this method is. Of course, if you’re an experienced user and know what you’re doing, then give this a shot and let us know what your experience with this is! Good luck!
