Your iPhone is just over a year old. You download the latest update. Suddenly, you noticed the battery doesn't last as long, and the phone seems slow. You're not crazy. Apple is doing that on purpose.
In New York, a teenager bought a used car. Days later, he took the car back to the dealership to complain that the iPhone dock wasn't working. Not only was it not charging his phone, it was scratching up the screen of his phone whenever he tried to put it in. Turns out, the youth's car didn't have a malfunctioning iPhone dock. It didn't have an IPhone dock at all.
