Past Nacrene City
You need the C gear early in the game,then when you get the game sync, which may be undergoing miantenance, you choose any Pokemon. They will go to sleep and you have access to the dream world for one hour exact every day. Try to find great stuff there, when you get a Pokemon there go on the wireless on the C gear and go to the entralink. The Pokemon you find in the dream world will join you there.
