Is this a bad idea or a good idea?

This one kid at school said he'd buy me a phone (Galaxy S3) if I gave him my school lunch everyday for the rest of the year. (I want a phone really bad.) But at the same time, I'm really skinny (5'4 and 89 pounds) because I don't get to eat often (my parents are poor) yet he's 5'9 and 140 pounds. He says he doesn't have enough money to eat lunch but he has Jordan's, an iPhone 5S (yes the 5S), a Mercedes, and he lives in a mansion. We made this deal 2 weeks ago. He said that the phone would arrive in another 6 weeks since the phone's being shipped from China. I want a phone really bad so I can fit in and not feel left out. (Everyone at school hates me and I always get made fun of for my autism.)

Added (1). Also the social workers think my parents are neglecting me.

Added (2). Also he said he'd stop being my friend if I decided not to give him my lunch. He already gets lunch from his other classmates so I don't see why I should have to give my lunch to him, but like I said, free phone.

Be careful dude this guy could be messing you around

You are going to get taken for a ride just believing everything someone tells you like that.

Don't believe him *** the other kids you are amazing just the way you are!

  • Would it be a bad idea to get an iphone 4? I can get it for free, but is it too old? Will I not be able to do things on it that I could on another phone? What are the pros and cons of getting it?
  • Would it be a bad idea to buy an iPhone 6 now? I have a Galaxy S5 and I want to switch butI don't know if I should wait for the next iPhone in the fall, assuming one is released in the fall.
  • Would be a bad idea to buy the iphone 4 now? I can't afford the iphon 5/s, but I did initially want the a samsung galaxy first. Anyway, I like to watch movies, listen to music and generally surf the web a lot. I also like to download a lot of apps and take pictures. Would the iphone4 be significantly inadequate now. If it helps I'm 18 and my parents can't afford and think it's morally incorrect to get me a iphone 5/s, but I'm not complaining.
  • Used iphone on ebay, good or bad idea? Thinking of buying a unlocked iphone on ebay. Is this a good idea? Will I have probs with activation? Can I use straight talk with it?
