Editing description/screenshots on a published app

I have published a free app on the android market. I want to edit the de开发者_JAVA技巧scription and add a couple of screen shots.

While the "Upload Aplication" screen on http://market.android.com/publish lets me make these changes & saves them too, they don't show up in the description of the app when I go the android market. Do I have to unpublish & republish the app (in which case I might run into version issues)?

Or else, how do I make these changes to description appear on the android market?

Ok, it doesn't show up instantly but after some time (in my case over 20 minutes!) Just wanted to share in case someone has the same problem.
