How to get a delivery report for text messages sent from iPhone 4?

Use iTunes to set ringtones

1) Select a song you like in the iT music library, right-click and open "Show Profile"

2) Open "Show Profile" Select the "Options" column after the "Introduction" window

3) Select a period of time that you want to make a ringtone, remember its time, and set the start and end time (within 40 seconds)

4) After setting up, make sure you right-click on the song and click "Create AAC Version". After that, a music excerpt that you cut out will be automatically generated

5) Right-click on the excerpt and select "In Windows Resource Management" "Show in the browser" will pop up a window

It contains your music selections

6) Change its suffix to "m4r" and double-click iT to automatically play it. It will be in iT’s ringtone

7) Synchronize iP’s ringtone

I downloaded the Ringtones ringtone creation tool from the app store and automatically converted it into m4r format, then saved it to my computer and then added it to itunes. Then you can see the ringtone under the device. Click on the device to synchronize ringtones.
