We often see benchmark filings for handsets that are expected, or for those that happened to have been previously rumored. As of today however we have one that appears to be somewhat of a mystery device. The handset is shown as the LG D801 and so far, we have yet to see any images. In fact, aside from a few small details coming from the filing, the LG D801 is mostly a mystery. That said, based on what we have seen -- it is a mystery we are interested in seeing the outcome of.
