We're pretty sure that LG did not list "fish tank" as one of the features of the LG GD900 Crystal. Yet, here is the handset with a couple of neon tetras living inside the keyboard thanks to the ingenuity of a man in China. This probably will void the warranty of the phone. In the video, we see this genius roll up his sleeves and turn his phone into a small aquarium. This is one thing that we're confident that there is no app for.
