Am I obligated to give him his money back?

A few months ago, I sold a guy at my school an iphone 4, for $200, which he then got activated with the phone service Revol. And now that the phone service is going out of business, he came up to me and asked me for the money back for the phone. Keeping in mind that the sale happened in early October, am I obligated to give him his money back?

Why can't I access a particular website while on Wi-Fi?

I'm having trouble accessing one particular sight (slashfilm.com to be precise).

The site is obviously working as no one else has the problem an I can access it just fine when I use my mobile data on my iPhone but I can't access the website on any device, computer or phone, while I'm not Wi-Fi. The only thing that loads up appears to be a grey background along with any links on the page. All pictures and regularly writing aren't shown.

Can anyone help? It's not like the website is being blocked by my router or anything. At I don't think it is.

Added (1). Sorry for the typo. That line in the second paragraph is meant to read "can't access the website on any device, computer or phone, while I'm ON Wi-Fi".

I dropped my iPhone 4S and it works fine?

I dropped my iPhone 4S from about a height of 12 inches.
I didn't pick it up straight away, but I noticed that the app I was on was still running fine.
Yet the right hand side of my screen was 2/3 grey. Up in the top right hand corner it looks like bleeding (black). While on the 1/3 of the screen left it's green(ish) but the phone is still completely usable to text/ring/use Wi-Fi/3G.
I turned the iPhone 4S off and now when I turn it on, the 1/3 of the screen I could see is completely filled with green. Meaning I can't tell if the iPhone is actually turning on or not.

Any advice?
(e, g) Take it to a shop for a new screen? How badly is it damaged, etc…
