Maemo
The 770, like all Nokia Internet Tablets, runs Maemo, which is similar to many handheld operating systems, and provides a "Home" screen—the central point from which all applications and settings are accessed. The Home Screen is divided into areas for launching applications, a menu bar, and a large customisable area that can display information such as an RSS reader, Internet radio player, and Google search box for example. Maemo is a modified version of Debian.
The 770 is bundled with applications including the Opera web browser, Macromedia Flash and Gizmo.
A critical bug has been identified which causes memory corruption when using the WLAN connection. This could result in system instability and data corruption. Owners of the 770 are encouraged to apply the bugfix; preferably before having used the WLAN connection for the first time.
