Ok .

I did see that.

I don't know of a QSD8250B SoC .. If there is one, I have no idea what
would be different.

It might be that the baseband processor is running different code
between the Nexus One and the Leo (i.e. different modem images), and
that code is programming the SoC differently between the two. Or it
could be a bootloader thing, does the Leo have fastboot ?
