To avoid restoring, you could overwrite
/System/Library/Frameworks/MediaToolbox.framework/N41/
or
/System/Library/Frameworks/MediaToolbox.framework/N42/
(depending on which exists - one of the two will)
with the contents of this file:

Make sure all plist files are overwritten. Reboot the iPhone after this.
