iPhone 3GS completely dead. Won't turn on won't charge. Reset buttons don't work
My iPhone 3GS is a paperweight. What happened is when I went to plug it in to a third party car charger (that always worked fine before) it made the charging sound then the screen suddenly went dead and now won't turn on. Holding down the home button and lock button to reset doesn't work. I took it down to the apple store where one of the staff plugged it into various charging sources such as a computer or wall charger with no success. He took it into the back and opened it up (not sure exactly what he did) and brought it back still dead. He said in the connector there was some corrosion and water damage even though I've never dropped it in the water or got any water in there that I'm aware of that would be enough to actually damage it. He basically said I have to replace the whole phone which will cost me since its not under warranty (I bought it 2 years ago from Rogers). Is there anything at all that can be done to restore it?
