App re-downloads restricted in iPhone OS 3.0?

The ability of users to re-download previously purchased apps over-the-air may be restricted in iPhone OS 3.0, according to a new report. Currently, users may purchase and then re-download applications an infinite number of times across multiple devices. Mac Rumors has posted a screenshot showing a new iPhone OS dialog box which informs the user that they’ve already purchased the item, and that they can download the app for free on their computer via iTunes, or can tap Buy to purchase the item again. The article points out that the restriction may be aimed at preventing the illegal sharing of applications across devices; it may, however, be designed to decrease the amount of cellular network data demand attributable to unlimited multiple re-downloads.
