Adran,
The Nexus One runs on the Google Android 2.1 open source mobile operating system. Fresh from the factory it supports Keyboard languages in English (U.S), French (France), German, Italian, Spanish, Portuguese (Brazil), and Display languages in English (U.S), French (France), German, Traditional Chinese, Simplified Chinese, Italian, Spanish, Portuguese (Brazil), Korean, Japanese, Russian

For Scandinavian letters you can download: Scandinavian Keyboard by Trygve Aaberge Also download the Finnish Dictionary by Tero Auvinen (made for the Scandinavian Keyboard). Although they are for the Android, due to the Nexus One running on the Androids OS (operating system) you should have no problems. I hope this helps and good luck!
