Recently I just got an iphone, and my sister has an ipod touch. She installed itunes at first and has used it download apps and music. My iphone has no apps or music on it and I want to download some. I tried yesterday and was told I need to upgrade my software to itunes 8.2 or later. My sister tells me that if I do she will lose all her music and apps as two ipod devices playlists arent compatible on the same computer?
I am very confused, and am very knowledge lacking in technical terms
If anyone can help I will be very grateful and rep them.
