Second: Itunes is installed on your PC (it doesn’t matter whether you have a registered ID or not). There are other tools that can convert formats. However, I personally recommend Itunes. It is simple and convenient... In addition, you need ifunbox, 91, ifile, etc. Any mobile phone assistant that can check the iPhone system files... (Here I am taking 91 as an example, the same explanation applies to others) Third: Make SMS ringtones. 1. Intercept any piece of sound you need (MP3, ACC, etc.). I personally recommend Kugou Ringtone Production Expert. The method of use is very simple. I will not introduce in detail how to intercept the sound clip here. (Note: According to Apple’s SMS ringtone convention, the intercepted sound clips should not exceed 20 seconds. I haven’t delved into whether there is such a restriction after jailbreak, but the SMS ringing for 20 seconds is about the same.) 2. Convert the ringtone format. (1) Open itunes and add the intercepted sound clips to Itunes: (2) After the addition is completed, start converting the format: click Edit>Preferences>General>Import Settings>AIFF in iTunes Encoder, click OK after selecting (there is a setting below the import enable, just select automatic). Select the audio that has been added to itunes, right-click on it to display a dialog box, select Create AIFF version, and then an AIFF will be automatically created. version audio. Save the created audio: Select the created audio, right-click the mouse, and select Show in Windows Explorer.

(3) Change the extension of the saved XXXX.aif file to XXXX.caf. Then change XXXX.caf to sms-received6.caf (Note: the number after received here can be selected from 1-6, depending on which ringtone you want to replace) 3. Replace the Iphone4 SMS ringtone. First close itunes, connect iphone4 to the computer, open any Apple mobile assistant (I used 91 as an example), find the file directory of the phone, the path is: /System/Library/Audio/UISounds, find sms-received6.caf and delete it, then delete the above The modified files in 2(3) are transferred to this directory. Enter the phone gt; Settings gt; Sounds gt; SMS ringtones gt; Original, what you see is still the original sound, then you select electronic music (No. 6), listen to it, has it changed... ..This way the text message ringtone is what you want... Note: The original ringtone name will not change, we just replaced the original file. The order of tritones-electronic music is 1-6 respectively. You can change the file name according to your preference... If you can't see the file extension on your computer, you can select the tool gt in My Computer; Folder Options gt; View gt; Hide extensions for known file types, remove the check mark, and then OK...
