Hard case for my cellphone

My little girls loves to play with my cellphone nowadays. She just discovered the Angry birds game and got hooked with it. It's okay for me to give her some time playing with my phone aside from her usual playtime with her other educational materials. What I do not like is when she gets irritated in losing the game, she would just drop my phone. Thanks to my dear husband, he got me this cell phone hard case to keep my phone protected from accidental drops. I can't take it when my phone will son get busted, I don't have a budget yet for replacement. I also need to teach my daughter to carefully handle the phone whenever she plays any game, or else she can't play with it anymore.
