While browsing the app store I came across this quirk in pricing.
On the list of top 25 apps the cost is $0.99:

But on the detail page the application is free:

If I was an iPhone developer and found my app being given away for free I would be a bit miffed.
If I was an iPhone user, and found that it was ther other direction (free on the list, cost in the detail), I would be equally miffed.
