I have a 1g ipod touch. i can't get any new music because my computer chrashed and i lost it all. I also can not get new apps because my ipod is too old. I would like a new ipod but i do not know if i should get a 3g (which is cheaper) 4g, or just save my money until the 5g comes out? If you know any new features of the 5th generation can you please tell me.
