You guys do know about the risk of "undisclosed" bootloader commands, right? They've been found in a few devices already...... allegedly a "mistake."
Uh huh...... :-)
(One of the reasons you buy a BlackBerry, by the way.... such nonsense isn't there!)
The ZTE does look interesting, but for the risk of that AND that you can't unlock the bootloader, which means you can't mitigate it by loading your own firmware (E.g. CM that you compiled personally.)
