The Ice Cream Sandwich leaks just continue to trickle out, over at the MyDroidWorld.com forums they have a dump of audio files from Ice Cream Sandwich which includes Ringtones, Alarms, notifications and UI sounds. Some of the alarms do sound quite cool. In the post on MyDroidWorld they`ve asked that we not host the file but direct people to the forum (which does require registration) so if you`re interested hit the source link and register to download the Nexus_Audio.zip file.
