Fommy.com finally has some video of their "Hybrid Silicone Skin Jelly Case." Many people were waiting for info on this case because it was supposed to combine a solid internal structure with a shock-absorbing silicone outer.
Now that there is video up, it does not appear that there is a metal or hard plastic internal structure, and that it is merely a silicone jelly case. Albeit, perhaps a firmer silicone than seen on more traditional silicone cases. Also, it appears that it is only available in an argyle pattern, and not in solid colors.
Looking at the video, it appears that the power, volume, and camera buttons remain covered by a thin layer of material. I'm a little worried that the only thing holding this case on is the very thin silicone strips. I have experienced several silicone cases tearing in the past. Although, again, this appears to be a sturdier silicone judging by the video.
