Long story short I had issues with my headphone jack. I tried using compressed air but it did not solve the problem. I used Q tips + alcohol in order to clean the headphone jack. This solved the problem somewhat but not entirely. However in using the alcohol I think some may have gone through the headphone jack to underneath the screen. As a result there is kind of a cloudy appearance at the top half of my iPhone 3GS screen. I currently have my phone in a cup of rice in order to remove the alcohol that may be present however there appears to be some bright white splotches and surrounded by a darker clouded appearance. The marks are similar to those which can be seen on a laptop monitor (e.g. ) I assume that the screen is now permanently damaged? If there are any changes to the situation as a result of using the rice I will update this thread. After searching the net for a while I haven't seen any cases of this happening. I found the problem with my headphone jack was probably caused by lint and that appears to be the case and I can't seem to get all of it out but I have gotten most of it and now the problem occurs less often than it did. Just posting to see if there are any tips for getting the alcohol out from underneath the screen. If the rice does not manage to do it I will probably have to take the screen off the phone and to remove the alcohol. I just hope the screen is not permanently damaged. This is a lame situation because my iphone has been in a case for the entirety of the time I have had it, I haven't dropped it and my cover actually has a flap that covers the headphone jack. The phone literally looks brand new with the exception of the now seemingly alcohol logged screen All advice is welcome and sorry for the long post. Thanks to those who read it.
