Cell Phone Case, Screen Protector, Reception Booster

[hooshpower]

I just bought the LG Dare. I want to know whether I should get a Hard Cover or a Silicone Cover. And I also want to know if there is a screen protector cover that acts as a mirror, kind of like the LG Shine. I've seen some sites claiming that they have it, but it looks fake. Also, I want to know if there is any way to boost your cell phone reception, for example that sticker that you put in your phone behind the battery. But does it really work?
