Custom ringtones SMS

SMS Notification is slightly more complicated than the Ringtones counterpart. SMS notification actually can’t be added, only modified. I also recommend shorter file for SMS notification. Here are the steps I take:

1. Trim MP3 files using Audacity (usually SMS notification should be shorter, roughly 3-4 seconds should be good)
2. Import the MP3 file to iTunes
3. Goto iTunes -> Preferences (for Mac) or Edit -> Preferences (for PC)
4. Navigate to Advanced -> Importing tab and set the “Import Using:” to AIFF
5. Find the AIFF file and copy to desktop
6. Change the extension to “.caf”
7. SCP to the iPhone using Cyberduck (Mac) or WinSCP (Windows) or any other SCP software
8. Navigate to the following directory: “/System/Library/Audio/UISounds”
9. Change one of the “sms-received.caf” file to “sms-received_.caf” where is an integer from 1 to 6 that is least preferrable
   For example: Rename “sms-received6.caf” to “sms-received_6.caf” to replace the Electronic with custom sound
   File name mapping to notification name:
   sms-received1.caf -> Tri-tone
   sms-received2.caf -> Chime.caf
   sms-received3.caf -> Glass
   sms-received4.caf -> Horn
   sms-received5.caf -> Bell
   sms-received6.caf -> Electronic
10. Upload the file on the desktop using the old name of that was changed
    For example: if “sms-received6.caf” is changed to “sms-received_6.caf”, upload the file using the name “sms-received6.caf”
11. Choose in iPhone the replaced tone
    For example: if you replaced sms-received6.caf, then you should choose Electronic
