some of the features are that the itouch has a link to EVERYTHING!!!!!!!!! including myspace and YouTube. you can txt but u cant call on the i touch you can pourchase games on the i touch like monkey ball and bubble rap. it is fast and easy to use with a touch sreen of course. its also an iPod! the i phone has alot of problems its kinda difficult sometimes u want to throw it out of the window. yes it has touch screen camera and u can call but i say thaat if u r looking to buy the itouch is right
