Apple has sold more than one million iPhone 3G S handsets, just three days after its launch.
The company also said in a statement that over six million people have downloaded the new iPhone 3.0 software for their iPhones, only five days after its release.
Steve Jobs, Apple's chief executive, said: "Customers are voting and the iPhone is winning."
Referring to the App Store, he added: "iPhone momentum is stronger than ever."
O2 also released a statement saying that on its first day the latest version was expected to sell an extra 50 per cent than when the 3G was released last year.
The iPhone 3G S was sold for the first time to queues of people on Friday in the UK, US and six other countries. It features voice control, a new camera and is significantly faster than its predecessor.
The positive news from Apple comes shortly after the less rosy article in the Wall Street Journal report, revealing Jobs was given a liver transplant just two months ago.
Jobs announced in January that he was taking six months of medical leave after he discovered his health problems were "more complex" that originally thought.
The Journal, and many reports since, claims he is in recovery but expected to go back to work soon on a part time basis.
IT PRO contacted Apple regarding these reports but it hadn't responded to our request for comment at the time of publication.
