Steve wants to know how to make a ring tone. Leo says there are two ways he does it - first use Garage Band to make it and then export it out as an m4r file. You may need to save it as an m4a file and then just rename it. It has to be no more than 40 seconds. The second thing is to use iTunes. Import it into iTunes or Music if you're using a current Mac. In Windows, though, it's still iTunes. Import your clip and select the 40-second clip. Then save it as an m4r file and move it into the TONES folder. Then sync it to your phone via USB. Not iCloud.
