iPhone 3GS in white, 16gb ?

Iphone 3GS, in white. 16gb. Works perfect but is scratched on back of case due to having for long time now. There is a little crack at bottom were you put phone charge in and out, I have been told this is normal tho as crack easy. Apart from this its in good working order. There is no charger due to little girl pulling out of wall and breaking the cables. Comes with box. Viewings welcome.
