It's not every day that you find the words "iPhone case" and "machined from a single hunk o' aluminum" in the same sales pitch. But that's what sets RockForm's Rokbed Aluminum iPhone 4 case (US$79.00) apart from its plastic, leather, or even wood competitors. Looking like something the Terminator would wrap his phone in, this metal exoskeleton manages to be strong without adding excess weight.
Installation isn't difficult per se (says the reviewer who's wrestled more than one bumper case on and off their test phone): remove two screws and separate the bottom end of the case, slide in your iPhone, and screw back into place.
"Wait a minute," you're probably saying, "I drop calls when my HAND touches the antenna bezel — do I really want more metal in contact with it?" Chill. RokForm's one step ahead of you: the Rokbed boasts a "Zero grounding precise fit," so no metal-on-metal action to wonk up your reception.
Aside from the premium price tag, there are a couple of caveats to note: the Rokbed currently fits the AT&T iPhone 4 and only the AT&T iPhone 4, and design changes on the recently-released white iPhone 4 meant that RokForm had to go back to the drawing board to make sure the Rokbed would fit that puppy as well.
