It wasn't Apple that killed Nokia; it was Android. Their big niche was cheap feature phones. When Android came along, suddenly, there were cheap smartphones, and nobody wanted cheap feature phones when they could get cheap smartphones. To be fair, Apple had a lot to do with forcing the UI changes in Android that made it popular, but the mere existence of Android in any form would have pretty much cut the legs out from under Nokia.
As for Blackberry, Apple didn't really start killing them until much later, as iPhone hardware wasn't really all that welcome in the business world until after Apple started adding stuff like mobile device management. I always found it odd that they were a hardware manufacturer, given that their hardware was fairly boring, and most of their interesting creations involved software and services. I'd expect them to reinvent themselves as a software and services company fairly handily, and freed from the shackles of having to build their own hardware, I'd expect them to do fairly well.
Ericsson got bought out by Sony, who still builds plenty of phones and other devices. Given Sony's size, I wouldn't count them out just yet. But if somebody does drive them out of the market, it will be Samsung, by undercutting them.
