Dan Rosenberg released his bootloader unlock method yesterday. This new method will not work for those of you on the latest OTA 4.1.2 update. If you are there and without root you would have otherwise been stuck. Dan decided to release another exploit to achieve root on 4.1.2. This will work on the Razr HD, Razr Maxx HD, Razr M, and Atrix HD.
