I'm going to be getting my first iPhone tomorrow the 3G S and I'm wondering if theres some kind of program that allows downloading and extracting of rar files. Lets say its some music thats in a rar can it be downloaded and extracted on the go so I can play it?
There is no downloading of files in this way. Everything must go through iTunes. There are apps that let you mount the iPhone as a wireless network drive and transfer and view some file types, mostly documents.
