Do I sell my new iPhone, or do I keep it?

I used my upgrade to buy my new iPhone 5 for 200 bucks. But iPhones are going for $800 on eBay. I really like my new Iphone, but I also really like the idea of making a $600 profit on it. What do you think? Do I sell it or keep it?

Added (1). I checked Ebay's previous auction page. People are indeed selling them for $800.

Added (2). I had an Android… The battery wouldn't last more than 45 minutes and it took ten minutes to open a web page. And it wouldn't let me download any apps because it would say that my storage space was full, which it wasn't. It would also beep every thirty seconds telling me that my storage space was full. And it would reject incoming text messages because my text message memory was apparently full, even though I had no messages in the message folder. Bad idea.

Sell it and buy an android: S

How will it make you feel afterward if you sell it? If you think you'll be fine with it, then I believe you should.

What happens when you sell the phone and spend the money then your current phone breaks? You will have to spend over $600 to get a new phone.

Just because they say $800 on ebay doesn't mean they are selling for it. Also it matters if yours is locked or not, if you got it with a contract then its locked.

Sell it and get an android. If you sell that phone you have to keep the contract open for 2 years and if it is on verizon you can keep it open for 2 years at 9.99 a mmonth by changing it to a dirt cheap plan and putting a dummy phone on it, or cancel the contract which cost quite a bit, i'm gonna throw out $300 but i forgot. So youll really be making 300 dollar profit.

we use to sell xboxs and ps3 when they first come out and make 200+ on each one when we sold it on ebay. Good times.

but just get rid of your i"phone" and get a motorola hdrazr maxx or wait for the new nexus phones to come out

Their selling it at full retail. Now lets say you sell it. You will have to buy another phone. But you will have to buy it at full retail

PPL are asking $800 for the iphone 5 on ebay, but nobody is buying.
you might get $450-$500 tops
