The technology company Apple says it has sold 4 million of its new iPhone 4s smartphones in just three days.

Apple executives say that is the “most ever” for a phone.

The new phone attracted considerable press coverage and boasts an improved camera, voice recognition, and other features.

While the iPhone is selling strongly, the combined number of phones on the rival Android operating system has a larger market share than Apple.

Another major smartphone manufacturer, Samsung, has said Apple’s new phone infringes on its patents. The Korean-based company has taken legal action in several nations trying to block sales of the Apple product.
