I phone 3g black 8gb *

I have an I phone 3g 8gb in black for sale as spares and repairs. it switches on when plugged in to the wall charger and shows the battery charging sign, which later on switches to the apple sign, it will not go further than this. condition wise it is good except two things one which is it has a small crack near the charging port which is common with these phones and also the volume button is missing. the phone comes on its own without a box and charger if interested ring/text me on 07742867506
