Q: Saving alert tones

Hello iPad Now,

Thank you for using Apple Support Communities. 

It is my understanding that you would like to know how to save your tones from your iPhone so you do not have to buy the tones again when you get your new iPhone. I love my tones as well and like to use them all my iPhones when I get new ones. I recommend transferring your purchases to iTunes on your computer. Then you can sync them to your new iPhone. 

These two articles have the steps to transfer your purchases and how to sync your new iPhone with iTunes: 

Redownload or transfer your iTunes Store purchases from an iPhone, iPad, or iPod to a computer

Sync your iPhone, iPad, or iPod touch with iTunes on your computer using USB

Cheers
