The Nokia N-Gage from 2003 definitely had OpenGL ES 1.0 as that was one of it's main selling points, 3D games on your phone to compete with the Gameboy. I remember Tomb Raider in 3D running on that. >Initially, ES support is coming in the form of software engines. Texas Instruments and Symbian have developed the 3D Graphics Library plug-in based on OpenGL ES 1.0 for Symbian OS-based mobile phones equipped with TI’s OMAP digital signal processors. In addition, Fathammer has integrated OpenGL ES into its X-Forge game software development kit (SDK), which is used to develop apps for Nokia’s N-Gage handheld wireless game unit. Here's some interesting presentations about early 3D on phones. Just look at all those GPU IP companies we had back then: ATI, BitBoys, Falanx, Imagination Technologies, Mitsubishi, Nvidia, Toshiba, and more. https://gfx.cs.princeton.edu/pbg05/PBG_mobile_gfx_pulli.pdf https://gfx.cs.princeton.edu/pbg05/PBG_mobile_gfx_pulli.pdf https://elinux.org/images/1/1d/Khronos-CELF.pdf https://elinux.org/images/1/1d/Khronos-CELF.pdf
