Motorola said: In terms of your question – we completely understand the operator requirement for security to the end user, and as well, want to support the developer communities desire to use these products as a development platform. It is our intention to enable the unlockable/relockable bootloader currently found on Motorola XOOM across our portfolio of devices starting in late 2011, where carriers and operators will allow it.
Let's hope this includes the Atrix. Otherwise, we're looking at a potential bootloader bypass via kexec. All they really need is a kernel that works.
