I disagree here- The Palm Treo was arguably the first smart phone, limited as it may have been. I had a 650 from around 2005 or so, and I actually kept that thing going until 2009 when I got an IPhone 3GS. The Treos and "regular" PDAs all ran the same PalmOS software. The Palm 600 was the first real smartphone and was released in 2003. I didn't pay for data, so used the PDA features much like you would a regular PDA- I had a dock and did a sync to my computer via their software. But I could and did put ebooks, mp3s on the device, synced my calendar, etc... it did the job, just much more poorly. You also had "Pocket PCs" made mostly by HP that were kicking around during this period as well. Ipaq's were only discontinued around 2011, the last model apparently being released in 2009: https://en.wikipedia.org/wiki/IPAQ https://en.wikipedia.org/wiki/IPAQ
