If you’re like most people, you probably have at least one iPhone and one iPad. And if you’re like most people, you also probably have music on those devices. But if you want to move your music from one iPhone to another without using a computer, there are a few things you need to know. First, make sure that your music is in the correct format. If it’s in AAC or MP3 format, it won’t work on the other device. Second, make sure that your devices are compatible with each other. If they’re not, you’ll need to transfer the music manually. Finally, be prepared for some trouble. Transferring music can be time-consuming and difficult - so be prepared for a long wait!
