My friend has an iPhone 3GS that is currently run from her work's laptop, with the twist that the music library is on an external drive. I'm going to build a new PC for her, and the aim is to have the iPhone run from that instead. So we need to move all the data across. So, what's the best way to move all the iPhone data across to the new PC so that the iPhone isn't wiped when I plug it in to the new PC? I'm not familiar with how the PC version of iTunes stores all the data, so I need to know what's where. Thanks, Dave.
