so my girlfriend cracked the screen on her iphone by dropping it on the corner of the phone. At the time she had a HARD case from the apple store on it, yet somehow it still managed to crack the screen. We just had the screen replaced by a third party website and want to know what kind of case would prevent this from happening again. I was always under the impression a rubber case wouldn't protect it as well, but maybe it absorbs the shock of dropping it better? Ideas? Suggestions?
