I have a Iphone 4 with 8 gigs of memory for sale. The back needs to be replaced because its been smashed.
I don't have the charger or the headphones with it but I do have the box.
It would look fine if you got a case.
Generally the back can be replaced for around $40, I would do it myself but I would rather just sell. Other than the back its in really good condition and it works great.
