Ok first you have to have a wireless connection....( you establish that by going to the "more" option on the menu and pressing "the wifi option"
after you have establshed a Wi-fi connection you have to go the the Town gate (its always at the north end of town).
THen you have to speak to The dog on the Right of the gate.......
HE will give you options (e.g. Invite a friend, I want to go out ect)
In that menu click on the option that says "friend Code"
He will then connect to the net and give you your friend code..

BUT BE WARNED!
You will have to get a new friend code everytime you destrow your town/move from town.......
AND ALSO!
Dont worry if you forget your Code
It will be stored for future use in the Friend code Section in your pockets!

HOPE THAT HELPED!
