Can you change the fruit to peaches in animal crossing wild world for the ds even if you have a different fruit already

well, all i know is that when i first got the game, i had oranges. but them i accidentally wiped out the game by starting it over. after that, i got back on the game, i had apples. so that probably means if you want a different fruit, you will need to wipe out your game. By different person altogether but at times when you look on your beaches you will see coconuts, or even apples that you can plant and grow...for example in my town i have both apples, coconuts, AND oranges growing in my town.
also when you send letters to some of the people in your town...put in a fruit as a present in the letter. most likely the character you wrote will reply with a fruit as a present.... well that's all i have to say!!! :)
Also, if Ican add on and can help others out by saying this, if you send one specific person ten pieces of mail (like for example Lobo the wolf or Bella the mouse) with a 100 bells in each, you should get fruit back from them the next day. Only send ten peices of mail to one person however. On one day I got from Bella a coconut, peach, pear, apple, cherry, and a orange. Also to get items, put 10,000 or 1,000 bells on the mail and you'll get some pretty cool items.
Ok, as well as this, which i am not sure works or not, you can do the far cheaper method; send mail to everyone in the town with 'this is a fruit gift' written. Attach your native fruit and send it off after a few letters, you'll get a new type of fruit, plant it and repeat, this time attaching the fruit you got from the first attempt ........ etc as well as this just to let you know if you get a coconut, plant it atleast 3 spaces FROM THE SAND, not in the sand :) PS cut down a tree and plant the fruits you get in there, THEN plant them where you want, that way if you muck up, and the spalings you plant die, you still have the tree to give you more ;) happy growing!
