I don't know if this message is too late for you, but I have had the LG CU515 for 2 days now and I really like it. Anyways it does have that annoying alert tone for everything you do. I finally found how to shut it off. Its under settings, audio and ringtones, alert type, other alert tones. So far I don't know if it shuts anything else off but finally that annoying sound for everything I do is gone.
