Description:

MP3 music can't be directly set as ringtone on 1 and iPhone4S, mainly because the ringtone music format of iPhone does not support MP3, but only supports M4R format, and the ringtone playing time can't exceed 40S.

2. The solution, of course, is to convert your favorite music into m4r music format, and cut off the music and cut off the playing time to less than 40 seconds. Finally, put the cut music into the iPhone4S ringtone library, which requires Apple's iTunes auxiliary tools.
