I found an iPhone 5. Can I sell it?

I found an iPhone left on the train. There's no contacts in it, so it must be fairly new. Its logged in on a Apple ID account and is with Sprint network.

Can I sell it? Or do I have to reset it first? If so, how do I reset it?

Am I spoiled or just blessed?

I just noticed that at school I keep getting called "spoiled." I'm definitely not spoiled, my dad and mom buy me stuff I I get grades over 75%. I'll list what I have.
- Iphone 5 and 3 other old phones. One Is my aunt's old Nokia I never knew how to use.
- Ipad and my own laptop.
- 2 Ipods.
- I have nice clothes from higher end brands.
- 7 UGGs (I ordered more and one store had a sale!)
- 5 coach wristlets.
- We go on a lot of vacations.
- I have 3 closets, because most rooms In our house have 3 or 5 closets.
- I have 25 purses, that I bought with my own money.
- My mom has a Ford escape, BMW and a hummer.
- My dad has a jeep, mercedes and a cadillac escalade. Our hummer and jeep were pre- owned and a good deal.
- I wear more expensive makeup, since It's more pigmented and lasts longer.
I get told "No." I'm In grade 8 and people keep saying "You're spoiled." "You're rich." Etc I'm not rich my parent's are, my dad Is a lawyer and my mom works In the finance Industry. So am I spoiled?
I pay for things with my own money, I do chores, I walk my dogs, I take care of my pets, I cook for my parents. I son't think i'm spoiled, I'm very grateful and happy everyday (unless i have pain or an Injury, now that just sucks) I want to get a job and save up $150, 000 for medical school and I want to fix my grammar.
So, am I spoiled?

Added (1). By the way our BMW and Mercedes are from 2009 and 2011. The 3 closets In my room, one Is for shoes, one for clothes and one for storage.

I found a iphone 4s, can i use it?

So today, i was walking and i found a iphone 4s on the sidewalk. I took out the sim card and reseted the whole phone. I asked my parents if i can you use it but they said i can't because they can track it if i use it. I will turn off location services. I said that i can but can i? I don't want to get tracked and i don't know the number because i already reseted everything.

What else should I want for Christmas?

I want an iPhone w/ Siri, a chocolate fountain, a puppy, a kitten, a laptop. What else can I ask for, I would get a job and buy myself these things but I'm only 14 and I'm too young to work in California, and all my neighbors don't need any jobs done so i don't know.

IPhone 4S app downloads extremely slow?

I just bought an iPhone 4S 64 GB. I have Verizon. I got it and activated it and everything. I have been going on the internet and made and received phone calls and texted and all that. But when I try and download apps the thing is just so incredibly slow it's hard to handle. I switched from an HTC Android phone which was so much faster. I don't think I ever used Wi-Fi once in the 3 years I had the phone because the 3G was so fast.

A few hours after getting my iPhone I tried to download a 45 MB app on 3G. I had 5 bars the entire time and I timed how long it took to just download and it was 9 minutes and 45 seconds! In my opinion that is just unacceptable. I don't mean to sound like a huge Android fanatic here or boast about them but my droid could've downloaded 45 MB in maybe a minute to a minute and a half. I have an iPad and iPod Touch which only use Wi-Fi but love them and have never had any speed problems. This thing can't possibly be this slow, can it? Any similar stories?

I got water in my iphone

My sim card doesn't work anymore?

I lived in Korea for a while the beginning of this year; left, came back, put my KT Olleh sim card back into my unlocked iPhone 4s and my phone read everything and all of my Korean contacts are back, and when I type a Korean phone number it reads it as a number (because of the different amount of digits) But I do not have service and under "carrier" it doesn't have anything.

IPhone 4S not playing videos?

When I try to play videos in safari, chrome… There's a little play button that has a diagonal line that crosses over the video not allowing me to play videos on sites. I did a power cycle, complete phone reset (I did not do a backup from iCloud or anything) erased all setting in safari and videos from any website will not play.
I have an iPhone 4S with the latest software update.
