You're talking to a former programmer here, so you'd better be careful when you throw out technical terms. I've schooled people before and I'll do it again...
Bootloader unlock is different than root. I have root on my Amaze, but still cannot flash radios because my bootloader is not completely unlocked. So that by itself is a problem. I know you can use Odin for Samsung phones and flash a radio anyway, but it's not the same as having Fastboot unlocked.
And as far as processors are concerned, clock speed is a very small part of it. The architecture and efficiency are key. The 4460 is superior to most processors out there today, including the one in your S2 and the one in my amaze.
Also, I was talking about the real Galaxy Nexus, not the Verizon one. You would have known that if you actually knew what pentaband HSPA means.
