Some key stats:
"Whetting consumers' appetites for the new iPhone is crucial for Apple. Since launching the first iPhone three years ago, the touchscreen device has become Apple's largest business, accounting for 40% of its total revenue in its most recent quarter ended Mar. 27.
Analysts expect Apple to sell about 36 million iPhones in its fiscal year ending Sept. 30, up about 73% from 20.8 million in the previous fiscal year. The Cupertino, Calif., company has been reporting triple-digit growth in iPhone sales and Mr. Jobs said Apple expects to sell its 100 millionth iPhone this month. But analysts said the iPhone 4 will face more competition, especially with the introduction of more phones that run on Google's Android operating system, including Verizon Wireless's Droid Incredible and Sprint Nextel Corp.'s HTC EVO 4G."
