Mobile workers could benefit from a new Bing application launched for the iPhone and iPod touch yesterday, which features new enhancements in voice search and location-based services.

The new app, available free of charge from the App Store, includes voice search capabilities which have already found their way onto Windows mobiles and BlackBerry devices, according to an official Bing blog posting.

“Just say ‘San Francisco weather’ for a quick result, or even say a full address for a map or directions,” explained the blog posting.
