A new jailbreak app called MultiTunes lets you sync with multiple iTunes libraries on your iOS device. Apple limits you to one iTunes library at a time by default, and while iCloud and iTunes Match make it easier to access your music from anywhere, some would still like to sync with different libraries without deleting all locally stored music first. That’s where MultiTunes saves the day.
The developer warns new users:
“Before downloading content from iTunes or App Store apps, make sure your default library is selected in this app. Otherwise, your content may not download properly.”
MultiTunes is really easy to use, and it’s a perfect way to sync music from different iTunes libraries. When you open the jailbreak app on your iOS device, create as many different libraries you want. When you select a different library, open the Music app and you’ll notice that you have either no music or an entirely different collection, depending on whether you’ve synced with iTunes or not.
When you change libraries and open iTunes, you’ll be prompted to “set up” your iOS device again. Don’t freak out, this doesn’t mean that all your info is about to be replaced. Simple add a name for your device again (just keep it the same) and everything will look normal in iTunes, minus your empty Music app library. Your device will need to be authorized with another iTunes account to transfer purchased, DRM-protected music, but you should be able to add tunes over smoothly otherwise.
If you want to go back to your original library, simply open MultiTunes again and select it. Your Music app will be switched back to its original state instantly and your device’s library will show up like normal in iTunes again. Remember that you’re using onboard device storage for these different libraries, so be wary of your capacity when syncing back and forth.
