My bf gave me his iphone 4, he was wearing it in his pocket with keys, no scratches. I sold it after a few months, bought a SGS 2 (used for a year), no scratches on it either. I've tried a few screen protectors but they either felt horrible to the touch, degraded screen sharpness or both. So I say - unless you abuse your SGS 2, you don't need a screen protector.
