Please follow this steps correctly as it may damage your device. This is a Nokia N900 applications guide if you have not followed the older one.

Extras

An easy way to browse and install applications from ‘Extras’ is by going to downloads.maemo.org from the Nokia N900?s web browser.

You should also enable the repository in Application manager so that the N900 receives update notifications for the apps. The Extras repository is supposed to be already configured in the Nokia N900 but is disabled by default. To enable, follow the steps please:

Go into the Application manager.

Tap the menu -> Application catalogs…

Tap Maemo Extras.

Uncheck Disabled.

If it’s not there, then add it manually:

Application manager –> Application catalogs –> New

Catalog name: Maemo Extras

Web address: http://repository.maemo.org/extras/

Distribution: fremantle

Components: free non-free

After you enabled the repository, browse through the Application manager.

EXTRAS-TESTING

Extras-testing holds applications waiting to be tested and passed to the Extras repository mentioned above.

NB:

Applications here might cause damage to your device. Regular users are encouraged to stay away!

To install the apps, activate the repository in application manager:

Application manager –> Application catalogs –> New

Catalog name: Maemo Extras-testing

Web address: http://repository.maemo.org/extras-testing/

Distribution: fremantle

Components: free non-free

EXTRAS-DEVEL

I shouldn’t even be mentioning Extras-devel because it could really mess up your device.

NB:

The software in extras-devel is most likely not ready for end users. Developers upload the newest version of their software to extras-devel for an ‘automatic and human Quality Assurance process’ before it gets passed to Extras-testing.

I wasn’t sure if I must add a plugin from the repository, but I took a chance, after hearing about account-plugin-haze. It lets me add my AIM
account on the built-in Conversations instant messaging app on the N900. It also supports GaduGadu, ICQ, MSN, QQ, Sametime, and Yahoo. It seems to be working fine so far and I hope to see it in the Extras repository soon!

To activate:

Application manager –> Application catalogs –> New

Catalog name: Maemo Extras-devel

Web address: http://repository.maemo.org/extras-devel/

Distribution: fremantle

Components: free non-free
