Mattycake, once a working english PokeSav for Black & White comes out, you can make your own. It's pretty easy to make them look legit.
Mayve, for the liberty pass, just use the friggin WFC mystery gift. If you are in another area, you are SOL. Wait for an english PokeSav.
Dsa, if you check codejunkies, theres some sort of shiny wild pokemon code. Dunno if it works or not, but its there. I believe there were earlier posts about the egg thing on the same thread/topic. Read the whole thread/topic. I don't remember if they found one or not.
And someone needs to find a way out of the 5th gym TRAP they made for people who use action replay. =.=
