Microsoft to update Windows Phone software

NEW YORK (AP) — Microsoft plans a major upgrade to its Windows Phone software this fall, ahead of the launch of the first Nokia phones to use it.

The revamped software contains a new, faster Web browser and allows users to switch quickly between applications, using a "card" display similar to the one in Palm Inc.'s webOS software.

Microsoft says the software, codenamed "Mango," will be available as a downloadable update for all Windows Phones sold until then.

Finland's Nokia Corp., the world's biggest maker of phones, announced in February that it would adopt Windows Phone and toss out its current smartphone software. Microsoft is paying it billions of dollars to do so, as it's trying to buy into a market now dominated by Apple Inc. and Google Inc.'s Android software.
