I dropped my iphone in the water, two days ago. I left it to dry near a light bulb for two days. When I tried to turn it on, the touchscreen only functioned partially, a bit less then the upper half screen functions, from what I can see, the rest still functions normally, it still connect to my Wifi and the speaker is working. Any tips on getting the rest of the screen to work? I for instance read that you should put the phone in a bowl of rice, should I try thing like that or is this end of story?
