Black IPhone 4 16 gb, Very good condition, Spares/Repairs +

I have a I phone 4 for sale. The phone is in very good condition and was fully working until i tried custom restoring it. The phone displays the connect I tunes . The phone was fully working before this. Im pretty sure its an easy fix fro those that are good with computers and this sort of stuff. The Iphone comes with a screen protector, back cover, cable and a plug. As far as im aware the phone should be unlocked
