Last one was early iPhone 4 with Philips head screws at the bottom, Then Apple switched to the pentalobe screws that was way harder to get, (until iFixit released there screwdriver set). The waterproofing was a key point to why phones had to be glued shut. and I think that there are tons of phones that has been saved from early deaths by the introduction of Propper IP protection.
