If you upgraded to an iPhone 6s, chances are the case on your old 6 fits just fine. But if the old case is waterproof, don’t go dropping that 6s in a puddle.
The iPhone 6s is taller, wider and thicker by 1/100th of an inch in either direction, hardly noticeable in hand but enough to compromise the protection on a waterproof case.
Catalyst, an accessories company favored by Apple users unafraid of a little water on their devices, has rolled out a new waterproof case for the iPhone 6s and 6s Plus.
