Actually, this method should root just about any Motorola phone running Gingerbread.  So not only will it work on the DROID3, DROID2, DROIDX2, and DROIDX, but it should also work on the DROID Pro and D2 Global when they receive an update – hopefully the DROID Bionic too.  We were inspired to write this for the simple fact that the D2 received Gingerbread last night finally, and within 5 minutes I was rooted.

Thanks to Framework43 and psouza4 for putting this together.  It couldn’t be any simpler than this method right here.
