Kindle Android - Refresh a book cover? I use the Kindle app for Android. I had 'bought' one of the classic titles which they have - War and Peace, which, like many of the classics, had no cover image.  

They have since updated the title on the Kindle store with a picture for the cover. I would like to update the title on my device so that it shows the cover art. How can I do this? 

I tried "deleting" the title (it then goes to "archived items") and then redownloading it but this did not work. I also checked in Quick App Clean Cache to see if there was a cache I could clean, but Kindle is not listed. I also tried doing a 'sync' from within Kindle. None of these steps has helped.

My device is a Samsung Galaxy S Captivate, running Eclair yet (I think I'm getting my Froyo sometime this month).

If possible, I would certainly prefer to do this in such a way as to not lose my positions in the books I'm reading.
You could try deleting the app cache. Go to Settings > Applications > Manage Applications and find the Kindle app. Click on it and then hit the button that says "Clear Data". This will clear cache and start you off at square one again with the app. Then see what happens.
