Does this sound like a fair trade?

I had an iPhone 4 yesterday that I have had since it came out, and it has been totally destroyed with cracks so I decided I'd go to my daddy's pawn shop and pick out a new phone. I found a super nice iPhone 5C, blue, 16gb almost brand new. Only thing is I have AT&T and this phone was sprint. So I post on my Facebook that I'd be willing to trade. Someone replied and said they would trade their 16gb iPhone 5 for my 5C. His is in good condition.
Is this a fair trade?

It is go for it!

They're the same thing. Actually, the iPhone 5c has a bigger battery. Make sure the iPhone 5 has not been reported stolen. Tell the guy if you can meet up at an AT&T store so you can connect it. Hope I helped.
