I don't have a keitai but i have had an apple. i have a version 2. Check out www.tamalove.pixelmood.com n click keitai. Dere's a growth chart an it tells u what da apple's called. i think it's 'RINGOTCHI' or summthin like dat.
Good job! you got Ringotchi! They are the best teens for odd numbered generations, like ichigotchi. I have two keitais and they are two of my top favorite tamagotchis. Congratulations, and if you take good care of ringotchi, you will get Furuwatchi, the flower tama.
