Motorola already stated it don't want and won't release any Bootloader unlock to old devices ... THEY DON'T CARE.
they had much much better selling devices like the RAZR , and the Atrix 2 (two phones that sold much better and have close hardware to the Xybord - same OMAP4430 ), and both of them have the Bootloader locked , and will stay that way until somebody would manage to do the impossible and crack it (something that as you know didn't happen on Moto's OMAP4430 devices.. unlike the Qualcomm ones).
