How Do I upgrade My iPhone?
I think you will have to buy it again. but why upgrade, there are so many application for the iphone that let you just stream you home library over the internet and listen to music (like SimplifyMedia) I have a library of about 10,000 songs…of course those won’t fit on my iphone…but with applications i can just listen to my songs over the internet from my home computer for free. Then of course there are all the radio apps you could ever want. I have the 8GB phone and only use it for movies (if compressed correctly and you chop off all the credits and ending credits you can make the main title about 500MB way smaller than if you put the whole movie on the device.) So in a sense you really don’t need the 16 GB if you know how to use the apps and such in the most efficient way.
