The eBay iPhone app is proving to be profitable for eBay, with the company realizing $380 million in sales through the iPhone within the first nine months of this year, said CEO John Donahoe, during a [keynote speech at the Shop.org](http://blog.shop.org/2009/09/23/ebay-ceo-discusses-mobile-customer-feedback-and-embracing-competition/) event this week.
The eBay chief said the online marketplace is making mobile a priority as it’s having a “a powerful impact on commerce and payments,” adding that about 4 million people have downloaded eBay’s iPhone app.
And, iPhone users aren’t just buying liquidated and collectible items. Donahoe said earlier this year a Lamborghini was purchased with the iPhone app and last month a shopper used their handset to buy a $150,000 boat.
