My Kyocera 6035 Smartphone (added to my collection in 2019)

• 20Mhz Dragonball EZ CPU
• 8MB memory
• 160×160 EL-backlit LCD (plus Graffiti touch area below LCD)
• Palm OS 3.5.2
• IRDA port
• Serial Hotsync port
• Built in cellular modem and phone functions.

The 6035 (released in 2001) is quite similar to the Qualcomm PDQ which was released a few years prior in late 1998 or early 1999, it was roughly equivalent to a Palm III in specs, where the Kyocera 6035 is roughly equivalent to a Palm Vx, so minor upgrades.  Both had a similar form factor with cellular control buttons that flipped closed over the bottom portion of the display, and when flipped open revealed the Palm PDA functions.
