Hi, does anyone have tried any of the scuba cases for iPhone? I need a scuba case for iPhone 5 and I was wondering if any of you have tried the TAT7 case on the iPhone 4 and can share your experience here. http://www.tat7.net/webshaper/store/viewCat.asp?catID=1 It seems they are developing a case for iPhone 5. If any of you know any other options available on the market I will highly appreciate your advice. I need a really waterproof case for scuba diving (around 10-20 meters) and not a waterproof 2m case like lifeproof or similars. Thanks in advance.
