I have been using the iP4 for about a month without a case. I don't have any issue with the antenna and really like the way the phone look. However I do find the square edges a bit distracting if not somewhat uncomfortable. My free Incase Snap Case arrived a couple of days ago. Well, with the case on, the bottom feel nice, but the top, where the edges meet the face of the iP4, is rather "edgy" and doesn't feel nice. So I went to BestBuy yesterday and tried out a black Incase Slider. It felt really nice: still quite minimal, softer edges, nice transition between the top edges and the screen. I had a Incase Slider on my old 3G so I felt right at home with it. It looks pretty understated, and that may be a good thing. On the other hand, I have been contemplating a Grove bamboo case: similar design, but a bit thicker (may be an issue). My thought: if I was to cover the nice design of a iP4 with something, I may as well do it with something beautiful. Does any one have both and can offer an opinion? two concerns come to my mind: (1) thickness of the Grove, (2) accessibility to the volume buttons - the Incase Slider is OK, but is the Grove any worse? By the way, I don't use a screen protector.
