Microsoft Corp. on Tuesday officially unveiled the newest version of its Windows Phone mobile operating system, which, according to the company, will make Windows smartphones smarter and easier to use.

The software company offered a series of demonstrations to illustrate numerous new features of the new Windows Phone software, codenamed Mango.

Mango integrates text message, e-mail, Windows Live Messenger and Facebook and Twitter chats in one place, making it easy for users to access them.

The new software will make use of a mobile version of Microsoft’s IE9 web browser, and will leverage built-in phone capabilities such as location awareness, camera and microphone to deliver more relevant search results.

President Andy Lees, of Microsoft's Mobile Communications business, said that the company kept the user in mind while designing Mango.

Speaking on the topic at the event, at the Tribeca Grand Hotel, Lees said, "We set about on a new mission to redefine smartphones to make it smarter, and easier, so that people could do more and have more fun.”

All eligible Windows Phone customers will get Mango for free sometime in the fall.
