CUPERTINO, Calif. ( TheStreet) -- Apple (AAPL - Get Report) unveiled its new iPhone operating system, which takes aim at Google in mobile advertising but left fans looking for signs of a new iPhone version waiting.
Apple CEO Steve Jobs kicked off the iPhone OS 4.0 introduction show with a few round numbers Thursday: 450,000 iPads sold, 600,000 iBooks downloaded, 4 billion apps downloaded to date, and seven new iPhone features unveiled, called "tent poles" during the presentation.
The 450,000 iPad total is a bit troubling since it means Apple has sold only 150,000 more devices in the past four days. On Monday, the company said 300,000 iPads were sold on the first day. The iPad sales numbers, while solid, are far shy of some of the more aggressive forecasts for the new device.
According to bloggers at gdgt covering the event, Jobs emphasized the joy the device seems to bring people who buy it, flashing pictures of a girl gleefully opening an iPad box.Tech watchers who were awaiting more details of a fourth version of the iPhone to run on the new iPhone operating system were left empty handed, however. New iPhones have accompanied the three prior operating system upgrades.
