The difference between the two phones is that the K790 supports GSM and EDGE, while the K800 supports UMTS and GSM.

K800i/K790 cellphones feature full support for USB mass storage recognition.

This means that there will be no need for driver installation on modern operating systems such as Mac OS X, Windows XP and Linux, as the phone will be automatically recognized as an external storage device upon connection.

The calendar is closely compatible with Microsoft Outlook.Mac OS X v10.4.9 added support for calendar and contact syncing under i Sync 2.4.This problem happens due to internal data corruption (caused by the phone), and can only be fixed by restoring ("flashing") the phone to its original software/firmware — meaning that all personal data will be deleted.Such decisions are labelled on the phone's display.The button in between the right soft key and the "C" button acts as a shortcut key, which brings up a user-customisable shortcut menu when pressed.Data retrieval also includes the ability to output files by infra-red and Bluetooth (as well as in network-transmitted messages) to other devices.
