Despite the growing pace at which the cell phone technology is moving, we are always wondering, how the phone of the future will look like. However, four creative designers (Lukas Doenz, Joachim Kornauth, Toni Weichselbraun, and Max Salesse), probably from the future, has unveiled the “Gravity Series” concept phone to give us the glimpse of the future. Featuring the hardware designed to be modular, the concept phone offers a huge HD display and HD output. So, if you thought a software update to resolve your phone’s reception issues should get a court’s approval beforehand, you are definitely looking at the bolt from the blue with Gravity Series allowing users to upgrade even the components of the phone. So, you never liked your 8MP camera phone? No problem, take it out and drop the new 12MP in!
