Seems to charge fine as as keyboard lights up but the screen does not come on. The screen is not cracked or damaged, so the fault is internal. I would have taken it to be repaired but I had another on standby. Cosmetically very good- few scratches around the sides, I believe the rpp on this is around 134 when working at 2nd hand value. If anyone can get it fixed, it would be worth it. This phone is 02 compatible and comes with working battery. Mint condition iPhone 4s 32 GB black. Received yesterday (Tuesday 16 October) from Apple Store Covent Garden as warranty replacement. Never used. Used charger and usb-iPhone cable included.
