I have recently upgraded from Nokia N900 to Nokia N9. On my N900 I had stored quite a lot of wireless networks from friends and family with their passphrases.
Is there a way to export them from my N900 and import them on my N9 so I don't have to go passphrase-hunting every time I get to a new network known only to my previous phone?
You may want to use gconftool (gconftool-2) to read out your network passphrases.
Or more easily (only for WPA, not for WEP passphrases) just install wpakey-editor.
But there is no such tool to ex-/import such settings. It needs to be done manually.
