I know there are plenty of guides and whatnot out there to root the Nexus One but aren't most of these for the T-Mobile version? (considering the AT&T version just came out)

What I'm asking is, does it matter that they are slightly different versions? I've seen before that when rooting you have to be careful for the G1 vs Dream, MyTouch vs Magic, etc.

So how does this affect the whole rooting process? Is it a big deal or does it not matter at all?

Thanks for the help!
