How much is it to activate a Iphone 4 through verizon?

I'm getting a job soon and they sell Iphone 4's for like 250 bucks on ebay so I was going to get one. How much would it be to start a contract and the monthly bills? Or is there another service that would be better? (Like T-mobile, At &t etc etc?) Thank you.

Iphone ringer and volume bar not working?

A few days ago I dropped my iPhone 4s in a sink of water. My otterbox case helped protect it so i don't think much water got in but my ringer and volume is not working. I can't listen to music unless i plug headphones / speakers into it. I tried cleaning the dock connector with a toothbrush multiple times but no good.

For Verizon Wireless, what is a full retail price?

Okay so my friend is 12, and she's getting her first phone. She wants to know what a full
retail price is. I would kinda like to know too. Does it mean you need to pay that price monthly? She's getting a iphone 4 or iPhone 4S she doesn't know. And what is the "if your are eligible or not eligible"stuff? I'm confused. She knows about the two year contract and and the termination fee, but I don't know how to explain the full retail price. I don't have a phone yet but I know some stuff about this.

Any advice?
Please no bad comments I'm new at this.
