If an app has already been approved once, subsequent updates to it shouldn't require approval and should be available straight away. I remember Quadoku at one point being in the 'Finished' section of the store (so it should have already been approved), but it's now been set to 'In Progress'
as of around a month ago. Could you have perhaps set it to In Progress by mistake? If so, you should be able to move it back to 'Finished' through the developer area of the site.
If this isn't the case, it's possible that there's a problem going on (I'm not sure I've seen an app move from 'Finished' to 'In Progress' before, so that could be something to do with it) and I'll see if someone can look at it after the Easter weekend.
