Change System sounds

The various system sounds are stored at /tpa/preset/system/sound. If you replace them with your own versions you can change the sound the phone makes for a given system sound. For example you can replace the noisy lowbattery.mid with something more subtle.Replacement sounds should have the same name and audio format (mid, mp3, amr) as the original, and be about the same length.To replace a system sound, delete the existing sound from /tpa/preset/system/sound and copy in your own version.
