There are photos circulating that are supposedly the next iPhone. If the photos are real, then it would certainly be an improvement upon the current model's casing. I like the shiny black just fine, but a matte black with a little bit of grip to it would be a great idea. Also, bringing back the metal casing on the back instead of the plastic one that we have now would make the iPhone feel much more sturdy which is definitely something I liked about the original iPhone. We will have to wait and see of course if these are in fact real photos, but for now we can speculate and try and figure out what kind of casing we would like the best. The next iPhones are likely to come out around the middle of the year since this is when Apple has stated as the normal life cycle of the iPhone. Above is the picture compliments of MacRumors.com
UPDATE - it turns out that this is in fact not the new iPhone case, but it was either a consideration by Apple or a way to identify a leak in there staff. In either case it would have been very nice for the new iPhone to have a matte finish, but hopefully they consider it for the next one.
