iPhone 4 doesn't charge, but loud speaker works?
Hello, I helped my sister fix her iPhone 4, as it showed the "Not Optimized for this Device" even though nothing was plugged into the dock. It turned out there was corrosion, so I replaced the dock with a new one. Everything went well, everything worked until I tried to charge it and nothing happened! :o The loud speaker, however, still works, though! What could be the problem? Thanks :)
Is this a good question?
