Yesterday I was unlucky enough to have a little bit of Sobe Lifewater spill on my iPad. Although most of it got on the screen, a bit of it may have gotten into the speakers. At this point the iPad is running normally and the speakers are ok. However, when I rotate it in certain situations I notice a bit of pixel flashing on the edges. This doesn't happen all the time, but it obviously never happened before the spill. Is this permanent? If so, is it a cause for concern in the future?
