What does 'do not disturb' do on the iPhone 5?

I've got a new iPhone 5, after having no end of problems with my old Android phone. My Android phone had a silent mode on it, but on my iPhone there's a setting in the settings menu called 'do not disturb'. At first I thought this was the name of iPhones silent mode, but there's a switch on the side of my iPhone which when I use it says the phone's in silent mode, and does mention anything about 'do not disturb'.

So is there a difference between the silent mode and the 'do not disturb' on the iPhone?

How to cancel US cellular service?

I just upgraded my phone to the Iphone, my parents had to sign a new 2 year contract even though we're under the belief plan and we should be able to cancel anytime. I decided I'm kind of sick of phones in general. I'm too hooked to the internet. I figured I would cancel my cell phone and just get a basic phone for texting and calling.
