Wireless, Iphone 4g | featured news

As promised, Apple early today began taking pre-orders for its new iPhone 4, although only the black model was immediately available. Around 6 a.m. Eastern, however, the iPhone 4 page on Apple's U.S. online store was returning an "Oops! An error occurred" message. Minutes later, the entire store went down. It was back up around 8 a.m., and a Computerworld editor successfully ordered one of the iPhones (in black). But by 8:15 a.m., the store was again down, displaying a "We'll be back soon" message.

Apple Inc's next-generation iPhone, which CEO Steve Jobs is widely expected to unveil on Monday, will have to really set new standards in multimedia content and function to wow Wall Street and consumers.

Apple Inc. hasn't said how much future generations of the iPhone will cost, but an editor of a technology blog said his site shelled out $5,000 to get its hands on a possible prototype.
