You don't need any friends to log onto WiFi.. Once you log onto wifi w/ the DS your using you can't log on with any other DS.. You must 1st when the game is at the Start Menu you must ckick on Nintendo WiFi Connections to set-up the internet connection.. So you can be newhere in the world as long as you can pick up a signal you can long on to WiFi(ex. @ your local mall, Buger King, Motels, etc.).
Next you start your game. Talk to the lady (1st lady to your right) She'll enable your Pal Pad(Found in Key Items, in your Bag)
Next log onto wifi To obtain your 12 digit WiFi exchangeable #.

As I said b4 it should Say:
CHECK ROSTER<-- See who you have registerd and other records
REGISTER FRIEND CODE<-- Register a Friend Code so you can Trade/Battle/Voice Chat or both
(YOUR NAME) CODE <-- Your Friend Code
Exchange Friend Codes with each other to register so you know who each other are... Your Done.
