Ok here's the situation: My iMac died last night. As a result, I had to dust off my 1st gen Mac Mini. I haven't used it it over two years. Once I fired it up, of course I had a major software update. The last thing I have left to update is iTunes. It's still on 6.0.2. My question is if I update to 7.7, and try to sync my iPhone, will it override my existing playlists that I created on my iMac. The library that I have on my Mini is about a third of what I had on my iMac. Is there a way I can add items to my iPhone without overriding what is already on my iPhone?
