I do this everyday when I go to the beach haha it actually works really well because you can still use it through the bag.
 
Your case just doesn't provide enough protection. For a mere $2 upgrade you can get the Double Guard version, which not only protects against all of the things yours protects against but also against freezer burn, in case you decide to go to Alaska.

I ordered a set of these after seeing this post. They charged my credit card over 2 minutes ago and I STILL haven't gotten an email confirmation! WTF GROCERY STORE??? I NEED THESE ASAP! They are screwing me! If I don't get an email confirmation AND a tracking number SOON, I am emailing the president of the company. That'll show them.

If they ever do arrive, I'm suspicious they might not be compatible with the retina display. Can anyone confirm?
 
If you go to West Marine boating catalog you will find generic waterproof bags that will protect your iPhone to a depth of 33 feet. The small one that an iPhone will fit in and work (except the back camera on an iP4) is about $19.99 + shipping. It comes with a lanyard to hang it around your neck like an ID tag. I use one when I'm around my boat.
 
Best solution for the beach, i do the same thing every summer except i use zip-locks as i do not care so much about water-proofing. Although a good thought indeed
