Please name these waterproof phones with replaceable batteries. None of my Motorolas or Treos were waterproof. I believe that harden phones may have existed but were not available to normal consumers. Maybe I’m wrong which is why I want to learn what phones you’re talking about.
The G'zOne made headlines being the first water resistant phone and it had a replaceable battery from the very start. The Fujitsu F-02D was another good example, with a fully-featured touch UI while still boasting something other than the slab-of-glass designs of today.
These phones weren't very popular in the west (Japan in particular had a large waterproof phone market, allegedly because people were taking them with them into the shower), but they have existed for a years, before the first Androids or iPhones became water resistant.
Phones like the Samsung XCover (the Android 2.3 one from 2011) were sold worldwide and featured a hotswappable battery. Over time these became bulkier and frankly uglier as they doubled down on how "rugged" they were, but the technology was clearly there.
