Some of the first accessories for the iPhone 4 have appeared on Griffin's website, six days ahead of the launch-date. The Elan passport wallet may not be as colorful as the err, Bumper, but it can store all your cards.
As well as the Elan Passport wallet ($40 / £30), there's also a Reveal case which has a transparent look for the front and back, and rubber siding to keep it safe. This is definitely the most discreet case we've seen so far for the iPhone 4, and one of the cheapest—it'll cost $25 / £20 when it goes on sale for the iPhone 4 launch. [Griffin]
