SafeStrap is a method of booting custom ROMs on the Droid Razr line of phones (which have a locked bootloader) by hijacking one of the system processes during the boot process. SafeStrap Official Thread
Testing a few things out, the binaries seem to work upon initial inspection, but since the Graphics driver is wrong (and I'm going to assume the touchscreen input itself as well), I'm not willing to attempt it yet as I don't have any kind of way to recover from a soft brick.

Now, I don't really know much how this works other than that which I have already described. I feel that once a custom Rom compatible with the International version is ready, we may just be able to get this ported over and working on our jailed phones...
