Iphone 4 16gb (slightly faulty) .

I have for sale an Iphone 4 16gb in good condition, tiny chip in the top right hand corner and a bit of cosmetic scratching to the back. It is mainly fully functional the only fault is the microphone occasionally doesnt work when your on a call so the other person cant hear you. Fab phone all other functions fully working!
