Using iPods, iPhones, and Apple TV with PowerTunes

If you own an iPod, iPhone, iPad, or Apple TV, you of course use iTunes to sync all your music and video between your computer and your device. When you create multiple libraries with PowerTunes, your device will "remember" which iTunes library it is synced with, even if you switch back and forth between different libraries using PowerTunes. If you plug in your device while iTunes has a library open other than the one the device is synced with, current versions of iTunes will still sync things like calendars and contacts, but will leave the music from the device's library on the device untouched. If you want to sync the device with another library, you can select the device in iTunes and go to the Music tab to tell iTunes to sync the active library with your device. This will replace whatever's currently on the device with the music and video from the current iTunes library.

When you plug in an iPod, if the iPod is synced with a library in PowerTunes' library list, a small iPod icon will appear next to that library, so you can easily see which library is the one the iPod is currently synced with. This feature applies to regular iPods, but not any of the other iOS devices; because of their different software, PowerTunes cannot detect which library an iPhone, iPad, or iPod Touch is synced with.
