You may have heard that a few people have been dissatisfied with their recent iPhone 4 purchases. Apple has gone out of its way to make it up to them (whether or not they've done enough is debatable), but that hasn't stopped people from complaining. Some of those people got lucky when they complained publicly on Twitter, because someone was listening. It wasn't Apple, but Samsung, who decided to try and convert some of its competitor's users to Samsung users.
