Questions about MB history...

[Cyroceon]

Has all MB that were 2.2 ghz been since Leopard, or should I make sure to look for MB062 or MB063 rev. B? I just am wondering because many sellers don't put the part number on the listing, just clock speed.

No. But if they don't give you Leopard, you can claim it for free (although you have to pay P&P).

Yes, the Macbook was bumped up to 2.2ghz, it is Leopard only, no tiger.
If a seller is selling you a Macbook 2.2ghz with Tiger it is a lie, because the 2.2ghz models cannot run tiger.
