How to make the best caf text message ringtone

Here is a very simple method of changing text message ringtones. This method comes from a crazy friend on the Internet. I would like to thank him in advance. If you follow the steps, you will succeed! 1. First use the Easy CD-DA software to convert the .mp3 format into the .aiff format. This software is easy to operate. First import your mp3 format ringtones, and then output them as aiff format files, that is: XXX. mp3 Software That is: XXXX.aiff manually rename sms-received1.caf Note: sms-received1 is the first of the six files corresponding to sms-received1-----sms-received6 under /System/Library/Audio/UISounds , these 6 files are the 6 text message ringtones of the iPhone itself. 3. Connect to the iPhone through WinSCP or iPhone PC Suite software, etc., enter the /System/Library/Audio/UISounds directory, and overwrite the sms-received*.caf file with your own sms-received*.caf(*=1,2 ,3,4,5,6) will do. It’s easy to understand and operate, and you’re done!
