Byline has made a similar move -- the Google Reader, erm, reader still has its paid version in place, or you can download Byline Free, which offers the same RSS functionality with ads included. I don't see an in-app way to upgrade, but if you try the free version and decide you'd rather support the developer directly, you can buy the full version for $4.99.
This is likely only the beginning of premium paid apps going ad-supported -- with the arrival of iAds in iOS 4, we'll probably see a lot more developers using Apple's advertising solution to supplement their development costs.
