We just learned about the KC780 a few days back
, but more details have emerged and it appears LG is going for the coveted "world's thinnest" title. The only new bit of information we have is that device will have limited touchscreen functionality. A tipster hooked GSM Arena up with pictures of the KC780 next to the Renoir, and apparently they're basically the same size, but hey .00001mm is technically thinner.
