I got this one a few weeks a go: http://www.sw-box.com/Stainless-Steel-Back-Cover-For-Iphone-4-Silver.html I instantly realised that receptions was hindered by the cover, where I used to get 5 bars I would get 3-4. Wasn't really bothered as there was still adequate reception. I soon realised though that in areas where I got 1-2 bars I now got instant searching and then no signal, with the phone just sitting there. So are there any metal back covers that don't hinder reception? If there are what is this one missing?
