This is getting really annoying and I dont know how to stop it. I have created a number of playlists on my iphone for various music. But once I plug my phone into the computer all the playlists are deleted/disappearing. Am I doing something wrong or is there a way to stop it??
iTunes, click the tab for your iPod. There's 6 boxes under "Options" that can be checked on the page that displays the device name/capacity/version/number. It's the last box.
