Series 80

Series 80, also known as S80, is a Symbian user interface used on Nokia's Communicator devices from 2000 to 2006. S80 was designed for 640 × 200 displays and QWERTY keyboards. It was succeeded by S60 3rd Edition on the E90.

1st Edition
The first edition is based on Symbian OS 6.0 and was used on the Nokia 92xx series.

The system is pretty barebones without a memory card, as most of the apps are contained on the MMC.

2nd Edition
The second and final version of S80 used Symbian 7.0 and was used on the Nokia 9500 Communicator and Nokia 9300/9300i.

Some 1st Edition apps work on 2nd Edition, but others crash with an error.
