Every time my iPhone (I just got used, but in bran new condition) gets slow or sluggish. Or when I hit the home button and it freezes up for a slight second and immediately switches to the home screen. I usually do a hard reset and that makes it seem go faster. Is that bad for the iPhone to do a hard reset that often? Could there being 35 apps on the phone be a cause of it getting slow? (Until I do hard reset)
