Sonastand - A machined aluminum acoustic stand for the iPhone 4 and 4S. It holds your iPhone in landscape, captures the sound from the speaker, and re-directs it towards you with enhanced clarity and volume, all without batteries. Its specially-designed sloped shape allows you to plug the charger into your phone while you use the Sonastand. ($39)
There's much argument over whether "liking" something means future brand loyalty or purchases. Like is not a magic button, it's much like a newsletter or mailing marketing campaign. As I've heard in real estate the idea is to "touch" the customer to remind them you're there. I believe ultimately this does add up to increased sales simply because awareness is increased.
