Root Available for T-Mobile, Sprint, and AT&T variants of Samsung Galaxy S III

While a method for rooting the Intonation version of Samsung Galaxy S III was discovered back in May, A working Rooting methods have been discovered for AT&T, Sprint, and T-Mobile Galaxy S III.

The method is the same for all 3 carriers and is pretty much what you're used to seeing for most Samsung devices. All 3 variants can be rooted by using Odin to flash a kernel and ClockworkMod Recovery to flash root.

Interestingly you can use the same files for the Sprint and the T-Mobile S3s, but the AT&T model uses different files. It's suspected that all 3 might be able to be rooted the exact same way, but right now it is only proven that the AT&T version works with the method posted over at XDA, so it's probably safe to stick with that.
