I have a dead pixel on my iPhone 4S and I want to take it back?

I have a dead pixel on my iphone and I'm taking it back tomorrow to try get a new one, I've had it for less then 30 days but the thing is I have a mm chip taken out the top of the back where the plastic bit hold the glass on to the frame of the phone. Will this make any differents in me getting a new phone back for this one I brought not long ago or will they refuse just cause the small chip? Please help I'm worried also will it be a refurb or a brand new phone they will give back?

Added (1). Could I get my money back from this also and I did go back and ask and they just said make an appointment with them which is tomorrow

I hate Windows 8 but loved Windows 7?

I hate Windows 8. Why? Here's why:
- The metro screen appears while I type at random
- If I leave the mouse too long close to the hot spots, either the metro screen appears or the search bar appears. This is an issue if I'm doing something like changing tabs or scrolling down.
- No Start Menu with folders but instead it has all of my programs listed
- Forced restarts. I've fixed this one but it drove me nuts. I nearly had a break down when I had a time limit and the computer forced a restart. Normally there are options like to push it off another two hours or something.

I've heard that it has better and safer design underneath it all, but I hate the user interface. I would rather go back to Windows 3.1 than to continue using the metro. I didn't have an issue with Vista or Windows 7. Heck I was fine with Vista after a few tweaks. Windows 8 is driving me nuts. If I wanted to use something like my iPhone, I would have bought a tablet.

Anyway, I can get Windows 7 Pro free from my school because it's part of some program with Microsoft. Dreamspark or something? I'm thinking about doing the clean install and getting rid of that garbage.

I have had Windows 8 for two weeks. What are your thoughts? Keep it or ditch it?

When I touch my screen a little hard and let my finger stay there for some seconds, some white and black lines appear and then the whole iPhone shuts down. After some seconds the apple logo appears and the mobile turns on again.
