I have never uesd iphone, but i have heared that it is a little trouble to use it because we have to use a third program to transfer owing to Apple allows iPhone users to transfer files from iTunes to iPhone but not support iPhone music to iTunes.
Recently I have just bought an iphone 5, and I am looking for a easy way to sync my iphone music to iTunes on windows, but it is failed to get some idea tool, because there are so many similar tools from google, it is very hard for me to decide which one to use. If you are an experience person, you must be very familiar with this, I am really looking forward to your helpful assistance.
