no you have to trade it from pearl, diamond, platinum, soul silver, or heart gold.
you can talk to the man in day care and he will say there has been sights of the leganary arecus at twist mountain
you can get arceus on Pokemon white only if you get arceus on Pokemon platinum and do poke transfer.

You cannot get an ARECUS by performing a glitch or cheating. You have to attend a special Nintendo event that'll allow you to download it. I may recommend Pokesav (a downloadable program to get Pokemon).
arecus is best it is a legendary pokemon and it has all the types of pokemon
