reading it now. it is very similar to unlocking the evo 3d with the htc method. it is not a true root in that you will still have s-on, but the bootloader will be unlocked and watermarked so that sprint will know that the phone was rooted at some point. also you will need to either learn adb so that you can flash a custom kernel or use the android flahser to flash the kernel.
so please guys just because we can unlock the bootloader does not mean you should accept the ota. DO NOT ACCEPT IT. it will make rooting and flashing a very big pain. and also this will void you warranty by doing it this way and sprint will know you were rooted. there is no way around that unless the revolutionary team can find a new exploit.
still gonna read this further and see if there is any difference to the method.
