I know this is a dumb question, but if I don't have a "Source URL", what do I do? When I click "about", it says I'm running "v2.6.2". I also tried updating from http://maemo.org/downloads/product/OS2008/maemo-mapper/ and it doesn't do anything. (I assume that means that I'm running the latest version.)

I'm on a N800 with (AFAICT) Diablo OS2008.

Thanks.
