Hey guys, I used to use a belt holster case for my iPhone 3G. Something like this: http://www.griffintechnology.com/products/elan-holster-metal-iphone4 What do you guys think about these type of cases? I ordered Bodyguardz, but now im debating, should I get a bumper or maybe a holster will provide better protection and may be even more convenient. What do you guys think? Any pros/cons?
