Is there any way i could upgrade from a 16 gb to a 32 gb ipod touch. Instead of having to buy a whole new one? Cause i am worries i might run out of space soon cause i have lots of music and i wanna load it up with some videos. I don't wanna buy a whole new ipod touch cause that would be like $350 to $400, and i don't have that kind of money. I barley had enough to buy the 16gb.
