Some people just don't read the original post and just posting unrelated problem solutions! I have the exact same problem as the guy who started this thread. Some water came onto the connector, it corroded over time and now im stuck with a constant stream of pop-ups which tell me this accesoiry isn't optimized for use with this iPhone. Now i can live with these messages, but the worst part is that i keep missing my calls because the $@^& thing won't make any sound! If you are at the same stadium as me please stop with trying to dry the iphone with rice, hairdryers or other junk. The damage is already done and we are trying to find out how to reverse it. I've been looking over the internet and tried some methods of getting these green eroded contacts back to work. Corroded contacts are allergic to white vinegar. But the problem with white vinegar is that it is a fluid which won't dry quick enough to not activate the white indicators in the iPhone. So i'm afraid this won't work if you still have the iPhone...
