There are already some iPhone 4 problems like signal los and yellow screen dots and now there is a new problem. Its not really a malfunction problem but its pretty weird, especially because Apple is so well known about their precision work. Apple has brought iPhone 4 devices on the market with their volume buttons reversed. The volume buttons function like planned, but the sign “+” and “-” are placed wrong. Most people wouldn’t even look at it but still its not what you can expect from Apple. Tell us if your volume keys are inverted.
