So i got a bit angry at a game and purposely dropped my iphone 4 on a wooden table (about a 3 inch drop) and the glass was already broken. As soon as it hit the table the screen went black, i tried to turn it back on but a few grey lines came up going across the screen, and now whatever i do the screen doesn't turn on. It doesn't vibrate when i flick the silent switch, and my ringtone doesn't go off when i receive a call/text/facetime, but it does make the charging sound every 10 seconds when i plug it into my computer and itunes DOES recognise it. Just need to know what i need to repair before i go and spend money on it and it still don't work. One more thing, i DONT have the money to buy a new phone, and please answer seriously!!!!
