The Treo 180g is a dual-band GSM smartphone made by Handspring.
The 180g is essentially the same as its predecessor, the Treo 180, except that it uses Palm's proprietary Graffiti handwriting recognition software.
It features a Graffiti area in place of the Treo 180's miniature QWERTY keyboard and shipped with Palm OS version 3.5.2H.
The 180g has a 160x160 monochrome screen, 16 MB of internal memory and a 33 MHz Dragonball CPU.
Two main models were produced, the 180 with a thumb-type keyboard and the 180g which uses the Graffiti handwriting recognition software, both were flip form factor.
