Did I do the right thing and make citizens arrest?

Last week while working in my shop, a young woman entered and instantly I knew she could be in to steal something. I had trouble recently with people stealing goods and I'm sick of it. Anyway, I was keeping my eye on her and she suddenly grabbed another customers iPhone and ran out of the shop. So I chased her down the street. I was never going to catch her as I was trying to run in tight jeans! So I shouted at people to stop her. Luckily another woman grabbed her and slowed her down. I then caught up with her and I wrestled her to the ground. I then sat on her chest and pinned her arms down with my knees. A few people then gathered around and I told them that she was a thief and asked someone to phone the police. Now this is the part were I feel really bad about the ordeal. I had to sit on her for about 15 minutes to wait for the police to arrive. She was shouting that she could not breath, so every few seconds id lift up a bit so she could catch her breath. When the police finally arrived, they searched her and found the stolen iPhone. The police congratulated me for doing this along with the small crowd of people. I now feel bad with what I did that day. Restraining someone like that is not a nice thing to do anyone. Do you think I done the right thing? Sorry about the essay by the way!

Is my iPhone safe to use in the condition its in?

I unfortunately dropped my phone by accident which left it with some pretty nasty scratches on the area outside of my screen. This area of the phone being where on one side you have the SIM card tray, and the other side where you have the mute switch and the volume controls. They are pretty rough scratches which makes me wonder if it would be safe to use my phone without repairing it. I don't want to hurt my hand when I'm using it, but equally I don't want to be paying to repair my phone if it is unnecessary to do so. Could anyone help me with this matter please as I'm really not sure what to do.
