Finally, the repository for Nokia Internet Table Orbiter was setup (thanks to Andrew Herron from Convergent Home Technologies Ltd) to provide one click installation for Orbiter. Actually, that possibility is available for OS2008 (Chinook and Diablo) only. There is no way to specify more then one repository in Mistral (I suppose nobody use it now) and Bora (it’s used on Nokia770 only I guess). So, if you don’t have OS2008 on your device you should add Maemo and Maemo Extra repositories first.
Anyway, with new one click installation the Orbiter can be installed on your device easily and quickly.
