Apple on Tuesday gave preview of its upcoming iPhone operating system which has new features such as cut, copy and paste texts.

The third version of iPhone operating system (OS 3.0) is now available for developers and will be open to customers this summer, Apple said.

The new software is packed with over 100 new features including cut, copy and paste texts within or across applications, a function requested by iPhone users.

iPhone customers can download the new software for free this summer while Apple's iPod Touch media player users will have to pay 9.95 U.S. dollars for the upgrade.

The software upgrade will keep Apple "years ahead" of the market competition, Philip Schiller, the company's senior vice president of worldwide product marketing, said in a statement.

According to latest figures released by Apple, the company has sold more than 30 million iPhones and iPod Touches so far.

Its groundbreaking on-line store now has more than 25,000 applications available to customers in 77 countries and regions, Apple said.
