You can use it to do a DS suitcase or to move a character from your DS town to the town on your Wii.
This is not possible. It can only be DS to Wii.
It isn't possible to move your character from animal crossing wild world to animal crossing city folk. The only type of connection between ds' and wiis is that you can download your town to a ds and then un-download it to another city folk game to visit another friends town. You cannot connect the ds game to the wii game whatsoever.
Sorry, but you can't get town themes in Animal Crossing City Folk.
On the menu, before you choose your character, you can choose DS Suitcase. This enables you to transfer your town easily.
No, it's not possible. You would need to do it through Animal Crossing: Wild World for Nintendo D.S. You would both need to have it. Go to the post office and talk to whoever is there, and select immigration. You will be moved to the town you wish to move to.
Yes. When you rebuild your town, you delete everything, and there's no way to get it back.
