I lost my iPhone that was in its’ OtterBox case back in January 2013, during a big winter storm. I was unsure of where, so was unable to find it. Since that time we have had -50 to -70 degree temperatures, a spring thaw, rain, and then heat, and many other different kinds of weather conditions…A couple of weeks ago my friend found it in a big mud bank. The OtterBox was steamed over on the inside of the box and was kind of beat up after being pushed around by a loader or snowplow. However, after charging the iPhone I found that it not only works perfectly, but had no lost data- since my photos were still there, and my contacts were still available. You gotta love that OtterBox for protecting my phone. I am spreading the word- such a fantastic tool. Thanks OtterBox.
