Does a bumper on an iPhone 4 stop the screen cracking when you drop it?

Bumpers do absolutely nothing. If you want something to protect your phone, get an otterbox. It's a $40 case but definitely worth it when it's full and total protection for a $600 phone.

I have an otterbox and I feel like I could throw my phone across the room and not damage it.

Hell no! The bumper is the lamest excuse for a phone case I've ever had! The best phone case ever is lifeproof. Quite pricey but its worth it. If you can't afford that, Speck makes awesome cases too. Bumper sucks!

Supposed to absorb some of the impact but i can't personally see that.buy a flip case.
