We came across a company called Gear4 at CTIA that has some really interesting iPhone 4 and iPad 2 cases. We are avid fans of the Angry Birds game and never thought we’d see the day when the Angry Birds turn into an iPhone case. The case itself is really slim and clips onto the iPhone or iPad. These premium cases come at a cost, though. The iPhone 4 cases cost $34.99 and the iPad 2 cases cost $49.99.
