To be fair Nokia, like Blackberry, was effed the moment iPhone launched. Elop hastened the decline but it was coming regardless.

It wasn't iPhone that doomed Nokia, it was Android. All of the sudden all Nokia's competitors could ship fairly good touch screen phones, while previously Nokia had a virtual monopoly on advanced mobile operating systems (barring BlackBerry in the US).

Granted, it was going to happen anyway, probably through Microsoft if Google hadn't commoditized that market first.

It's not quite the same, BlackBerry was mostly a 'phone' company and not a 'full telecom' company, in terms of hardware the produced. Nokia has other products that are more b2b than b2c.

Nokia has existed for over a hundred years. The success of its phones made it a major name and a ton of money in the early 2000s. Its other lines of business have continued to operate quietly. But it's no longer the force it was.
