It appears that stories circulating the internet about eBay iPhone scams made some waves in the eBay waters. eBay is now banning all pre-sales of the popular iPhone to prevent fraud.

A note on their website gives the specifics:

Apple iPhone Pre-Sales are prohibited. This highly-anticipated device will be in high demand after the US release on June 29th, 2007. Prior to the release of similar high-demand electronics, we saw a high number of well-intentioned sellers unable to meet their pre-sale obligations to buyers due to restricted supply, as well as an increase in fraudulent listings for these items. To prevent similar problems with the iPhone, eBay is prohibiting all pre-sales of this device. Source: eBay
