The company, which is making a focused effort to win over consumers in Asia where rivals Samsung Electronics Co Ltd and other Android manufacturers dominate, said in the invitation that it will host a breakfast and presentation at its Cupertino, California headquarters. The event will present a key moment for Apple to fight back growing concern that it is losing its innovative touch, nearly two years after the death of its iconic co-founder and chief executive, Steve Jobs.

Apple is expected to launch two new models this year - widely referred to as the iPhone 5S - with new fingerprint technology as well as a cheaper version in plastic casing. Apple plans to dress up the phone in a range of five or six colors to differentiate it from the more expensive model that has traditionally come only in black and white, according to the sources.
Analysts say that the company needs a cheaper phone to drive faster growth in markets like China and India, and to counter Samsung's edge in having a wide range of devices at varying prices.
