I'm looking for a waterproof case for my iPhone 4s. But as i am looking at the specs of the cases they say they are waterproof in up to 6 feet of water and for 30 minutes.what does that mean? does it mean that after 30 minutes water will get into the case? And what about the six feet? does that mean if my phone is under 7 feet of water the seal will break? I don't understand this.please help me.thank you. :)
