Hello! I'm interested in your iPhone.  Can you tell me how many people have used the phone and if it's ever been wet?
Are you interested in the phone?
Yes!
I bought it originally and no it has never been wet. I don't even take it to the bathroom when shower because I didn't want any moisture to affect it.
I've done a little digging, since I'm looking to buy this sort of phone for my teenager, and it looks like these are going for approximately $190 online.  What are you asking?
$350 and it has been checked by the local phone store and I had them set everything back to factory like new. I also have the manuals, a car charger, and earphones that I can put with it.
That's a little steep for me.  If you throw in an otter box (protective casing) and will pay or postage, I will give you $320.  
I actually had a case for it. It is yellow and I can ship it. That's not a problem. $320 is a great deal for you. I'm sure your teenager will be thrilled.
