Apple's

iPhone OS 4 update is expected to arrive today, bringing the tech giant's eagerly-anticipated

iOS 4

to iPhones, iPads and the iPod Touch.

previewed the iPhone 4.0 operating system

in April, and rebranded the software iOS at the company's recent Worldwide Developers' Conference (WWDC). New features include application multi-tasking, a mobile advertising platform called iAds, and a unified mailbox.

(T) - Get Report

have faced a

deluge of demand for the new iPhone 4

, which will run iOS 4.

In a statement released on Wednesday, Apple explained that it had taken more than 600,000 pre-orders for the new iPhone 4, along with AT&T. This, it said, was the largest number of pre-orders it had ever taken in a single day, and far higher than anticipated.

Despite the frustration felt by many customers, the phenomenal demand for the new phone is a

big positive for Apple investors

, apparently heralding an onslaught of new revenue.

Apple, which is facing

an onslaught of phones built around Google's (GOOG) - Get Report Android operating system

, is clearly off to a flyer with the new iPhone 4.

During Apple's recent second-quarter results, iPhone shipments climbed a massive 131% compared to the same period last year, reaching 8.75 million devices. iPhone revenue also rose dramatically, reaching $5.45 billion, compared to $2.43 billion in prior year's quarter. iPhone sales now account for around 40% of Apple's total revenue.
