The Snapdragon S4-based One X has been rooted, thanks to kennethpenn of XDA-developers. This isn't a bootloader unlock, but it is full root, so apps like Titanium Backup will work just fine. It's also been confirmed to work on the AT&T version (I'm enjoying root now yay!). The developer has been nice enough to make a neat little one-click package that will do the work for you. All the relevant files are installed automatically, and when it's done you have Super SU installed, too. So no confusing ADB commands to follow on this one. The usual warnings do apply, you're rooting at your own risk and anything that happens to your phone is your fault and no one elses. Are you also enjoying root? Let us know in the forums.
