Was it the first smartphone? I would call phones like the Palm Treo and later BlackBerries smartphones. There were even apps, but everything was lot more locked down and a lot more expensive.
It's not just you; at the time these products were available, _everyone_ called them smartphones. Emphatically, Apple did not bring the first smartphone to market, not even close. They were, however, the first to popularize it beyond the field of nerds into the general public.
>it became a huge sales success for Nokia ... It managed to outsell rivals such as LG Viewty and iPhone.
However the iPhone got better.
And just plain... bad. The entire experience didn't have that "feel" that Apple turned into reality. It's comparable to today's AI landscape—the technology is pretty neat, but using it is a complete slog.
Edit: There were also the limitations of that era that held devices back in general. WAP internet[1] was awful, but most mobile services were too slow for much else.

The entire device was a regular Linux machine.
The 770 was released in Q4 '05.
They definitely fell within the smartphone category, but oddly the first few iterations lacked GSM radio.
