Just uploaded to extras-devel a very simple utility to browse sqlite databases on the n900. I created it mainly to help me develop/debug my other applications.

It allows you to browse databases created by other applications or create new sqlite databases and run sql queries against them.
It automatically detects sqlite database files regardless of the filename extension and allows you to browse hidden folders.

Not sure if it will be helpful to non-developers as it is but, if nothing else, some people may find interesting to see what other applications are storing on their phones.

As always, please let me know your comments/suggestions....

Known Issues:
As now you can edit the data in a table but the changes will not be saved to the database.

Notes:
I tried to find a application that I could port to the n900 but didn't find anything suitable:

• just found this one for the n8?0 but it seems to be written in python
• QtSqlView is pretty simple but was the closest match to the n900 - unfortunately adapting the UI would be almost as hard as starting again. I copied the SqlHighlighter implementation from it and used it as an inspiration. Timo Bingmann: Thanks!
• Sqlite Database Browser is probably the most complete I found but it seems to depend on qt3
