The iPod touch 3 was even more successful than the other 2 iPods because it has even more features than the 2 others because it has a bigger screen and it has more data than the other ones. When it was first released it was released a little after or at the same time that the update came out so it got more features and better connection than the other 2 iPods. it was released in 2003 and the screen was thinner and the whole thing was thinner and a little taller.
