Bad news root crew, the DROID 3 has a locked bootloader
software updates to unlock bootloaders starting late in 2011. Unfortunately, it's barely mid-2011 right now, so change is still on the horizon for all except Atrix users, who apparently should have unlocked bootloaders with the Gingerbread update.Motorola has said that it would be offering
Since the DROID 3 is packing an OMAP processor, that means it most likely has eFuse built in which will brick your phone if you attempt to unlock it. That said, eFuse isn't a death sentence for rooting. The DROID X wasn't able to be unlocked, but it did get rooted a few weeks after launch.
