Worried about the work phone while on the boat so thought I would try to waterproof it. Did some research and bought the Aquapac for the Iphone4. In the past I always used a Ziploc, but you lose 1-$400 phone and that is alot. I trialed the Aquapac in the kithchen sink with $10 in quarters as a weight euivalent and no issues. Then I put my Iphone in, nerves going, and all turned out good! Bottom line, hope the phone never hit's water but if it does it will be protected and pray that it works! $30 is alot better than $400.
