Wanting to root and unlocked phone

[Barrios35]

My phone is unlocked and I use it on AT&T. If I root it and change OS I am assuming it will lock itself again? Is this true?

Nope, one has nothing to do with the other. Mine is unlocked too, and I've flashed roms a few times since.

I know someone who has mytouch 3g and he wants to sell it (he got the galaxy S). Can you unlock mytouch 3g?? How?

Yes there is a way to unlock and call Tmobile for the key.

Is there a way to find my unlocked code on the device itself? Just as a back up in case some thing goes wrong? It is already unlocked.
