I dropped my iphone 4s in a hot cup of tea the other day and at first the screen worked and everything but after it went completely blank then i took out my sim card and i still havent put it back in. now the screen is just black but it still makes sound and everything. i can even slide my finger over where the unlock thing is and i can heard it unlock. so the only thing wrong is that the screen wont come on. i put it in rice overnight the night i did it and i had it with me all day the day after without rice and i put it in rice again for 24 hours and just took it out a few hours ago and the screen still isnt working! can someone please help me!?
