What anti theft iPhone app that uses the camera to capture thief?

I have an iPhone 5 and I have the "find my iPhone" app on there if it's lost or stolen, however, is there another app (without jailbreaking) that also allows you to take a photo of the thief if they try to use it? I tried using Prey and could not figure out the application at all. Maybe it's just me… Any suggestions?

Why does everyone hate the iPhone?

Like the internet is just full of people that be like "iPhone suck" and "iPhones are overated" and "Steve jobs was stupid" and stuff. Like why? I see people with iPhones all the time. I actually played with the iPhone 5s at the store the other day and it was pretty awesome. Like 64 bit processing and a fingerprint sensor? A slow mo camera? Sweet! Why does everyone hate iPhones? They seem to be very nice phones.

Can I still track my Iphone if I don't have the app?

My phone got stolen, I don't have the find my iphone app installed but I logged into icloud and I can see my phone among the devices but it's offline. My phone can't be turned off because the sleep button doesn't work and the battery was almost full when it got stolen which wasn't that long ago. It does have a passcode but I'm worried sick that the person that stole it has something evil in mind ( like looking at my pictures or my personal details etc.) This happened at school so it's very likely that a teenager stole it and another girl got her phone stolen (our purses were in the changing room and someone went in and stole them). If I remember correctly, I had the find my iphone option turned off in settings because I was trying to save battery and I don't even have the app installed. So I guess my question is can I track it if the thief connects to Wi-Fi or not?

Isn't it creepy to buy a band's lead singer's iPhone?

The lead singer of my favorite band is selling her iPhone on Ebay and I wanted to buy it but I don't want to be creepy.
She has a YouTube channel and asked if people would buy it and they said yes and so it's on sale now, but I don't want to buy it and tell my friends and then they call me weird or something. It is my favorite band and I was going to get an iPhone anyway, so I thought "why not?"

Is it creepy or am I just being paranoid?

How to get grease out of my iPhone?

I was draining grease off my hamburger the other night and I accidentally spilled it all over my phone. Everything works but the speaker. I can't hear it ring I can't hear it when I get a text. I don't hear my alarm (which is a big shame since I use it for work) and when I talk on the phone I can hear them just fine but they can't hear me at all. I gave it a couple days to dry out but Thant didn't work. Plus it's grease not water it probably, y won't dry it will just harden up inside my phone. Any suggestions on what to do to make it work. I really hate it get a new phone. My contract is up at the end of the next month but I hate to go a month with out a phone
