Hello kinda new to this but was just curious as to what perks 2.1 android will have over the 2.0? I currently thinking about purchasing the droid and have heard talk about the 2.1 being great but no real clear details on what it will offer over exsisting OS. also the moto droid has 3 customizable home screens i have heard rumor that it will go to 5 has anyone heard the same thing?
