The algo used by Apple to calculate the rankings take counts (most probably) of the past 4 days of sales. My suggestion is now that you are up there to push sales as much as possible. A sale would definitely help, maybe $1.99 ($0.99 is synonymous of low quality) and see if you can get any friends or people you know to download the app right now. See if you get at least in the top 25, so that your app will show up in the first page of apps on the iPhone.
