I accidentally fell into a pond while fishing the other day and my phone was in my shorts pocket. Some error message came up on boot up afterwards. I soaked it in rice for hours and eventually it worked fine. I then updated my ios7 beta 4 to beta 5. Ever since then sometimes the touch screen on my phone randomly stops working completely. If I press the lock button and unlock it though it works fine after that. I was just wondering if it was an issue from getting wet or maybe an ios 7 beta 5 thing? When the touchscreen works it works perfect, but when it doesn't it doesn't work at all. Any suggestions?
