IPhone 4 for iPhone 5 trade in?

I have an iPhone 4 and its 8g and I wanna trade it in for an iPhone 5.
it has some cracks not bad but it works fully!
I will trade in my 4 but I wanna know how much more cash it's gonna cost to go with it to get the 5. Any ideas?

I've recently traded my iphone4 for the 5. Fully working, no cracks. Perfect condition aside from the fact it was used for around 7-9 months. I can remember paying around 85 dollars with the phone for the 5.In your case, your phone seems to be alittle beat up. Cracks can't be fixed. So i believe they may bump up the price around 30-50 dollars. But i'm not completely sure. It may also depend on what service provider. Ask your provider yourself and see what they expect.
