Hi all, I've been looking for a new replacement back cover for my iphone4. Specifically, I am interested in the one I saw from gizmodo a long time ago, it looks to be of high quality: http://cache.gawkerassets.com/assets/images/4/2010/10/gizmodo-iphone-verizon.jpg Essentially I am looking for a brushed flat aluminum back replacement cover, not the rounded version. I've seen a lot that look similar to the one from gizmodo from cnn.cn and sw-box.com, and also from various sellers on ebay. Are they all the same? Do they come from the same source? I need some help, where should I buy it from? Is there a general consensus of which seller sells the best quality one? I've also heard some of these back cover replacements interfere with reception and/or the camera lense/flash. Thanks!
