Dropped my Evo; screen broke. I have never used a case but apparently I need one for this phone. I use an extended battery. What is the best way to protect the screen from breaking? The only case I have found is the Seidio extended but that protects the back, which I don't want. Does it also offer screen protection in the form of keeping the screen from hitting the ground if dropped? Is there a rubber bumper case that would do what I want? Any suggestions from anyone?
