Hi could someone help whilst my iphone 3gs was on charging i heard phone vibrating and i went to look at it and it was display a message saying ios 6 then when u swipe accross the screen it says connect to itunes. But once i disconnected it from the power the phone died and i cant get it on again. If i plug it into laptop the apple appears on screen then dissappears then just continues to do that. If i plug it into charger it goes back to ios 6 screen like before. Ive changed the battery and still the same has anyone any ideas thanks
