I did tonight on carpet, with the Speck PixelSkin on. I had a Luxmo Argyle TPU case on that I absolutely love for slimness but I dunno I'm clumsy with cases at times so I think I might rock the PixelSkin to take hits and just use the Argyle when I feel up for it. Plus I noticed the chunkier cases result in no flaw in reception. The TPU and other slim cases, while do not allow for the death grip and slow the reception issue process, still decrease the reception somewhat. I think it's because you grip it from farther away from the antenna with the bulkier cases.
