Refunded a buyer on ebay and not sending an item. Ok?

So I was selling an iPhone on ebay and someone told me they wanted to give me £230 for it and I said ok and have now received the money and agreed to send it to them. When I ended the item early, it ended it as "sold" to the highest bidder and then opened a case to cancel it. I also sent a message to the person saying not to pay for it and if they do I will refund it as I'm not able to sell it to them. They sent payment anyway (I assume they hadn't read anything as it was pretty fast) so I refunded them and they got their money back, I then emailed them saying that I have refunded them and not to pay again as I'm not able to sell it to them as I have sold it to someone else. Is this ok?

Plugging iphone in for the first time?

About 2 months ago I got an Iphone, and at the time my computer was being fixed so I have never plugged the phone into a computer. I have music and videos, app, pics etc. On it and I want to know that now that I have stuff on it, when I plug it in for the first time will my stuff erase? My phone has never been plugged into a computer before, ever. BUT my ipod (touch) was synced with my first computer (wich crashed so I had to get a new one.) and I read that if you plug and ipod/iphone into 2 computers it'll erase it because your library is only supposed to recognise one computer or something like that?

Can't find an app on the appstore on iPhone?

I have been watching videos on what's on people's iphones and I've seen cool apps and most of them I could find on the appstore with no problems but a couple of them don't come up on the search even though i'm spelling them correctly. To be more specific, the apps that I can't find are Pandora (the radio app) and the fooducate app (scan items and see if they are healthy). I have a feeling its because I live in Canada and these are US Apps but thats just a thought. Please help me with this problem.

Added (1). BTW if it helps, I have the iPhone 4s. And i thought it was because i live in Canada because I can't even ask Siri to find me a place so…
