mute/services questions regarding Audiovox CDM8900

[DestroyerX]

Hi, I recently bought an Audiovox CDM8900 from my local Verizon Wireless place. I had some questions about it that I couldn't find the answers to in the manual, and I thought you guys might be able to help me.

Sorry if I'm repeating a topic that was already covered.

Does the etiquette mode turn off all sounds when it is activated? If not, how do I set the phone to stay muted all the time? How do I keep etiquette mode on? When I switch etiquette mode on, and turn the phone off, the phone forgets that I set it to it, and it makes that little tune and all the regular noises after I turn it on? How do I turn off that annoying tune when I turn off and on the phone? Also, will my carrier, Verizon, charge me money if I send pictures? Will it warn me on the phone before I do it, or will it just tack the charges onto my monthly bill?

Thank you so much for all of your help,
