anyone know the difference? i got this from http://wikee.iphwn.org/sgold_bootrom:bootneuter BootNeuter is completely reversible (as is all of Pwnage). This tool demonstrates that an application with root privileges can erase and reflash any bootloader. Be careful what applications you run, and never run them from a ramdisk (which is disintegrating as its being used). Unlike the main s5l8900 CPU, the S-Gold can actually be bricked A neutered bootloader survives iTunes updates, even updates to 1.2.0 (aka 2.0). Unlike unlocking which requires a new patch for each firmware version, you only need to neuter once. As effortless as BootNeuter makes it seem, bootloader flashing should not be taken lightly. BootNeuter won't reflash your bootloader if it detects that your desired bootloader settings match the current settings (for instance, if you are only changing the baseband lock status).
