So it was inevitable and bound to happen some time, but Live Search Mobile is being phased out in favor of Microsoft's Bing service. Microsoft is investing a lot of money in the new search engine with even some witty television commercials running. If you happen to still have the software, you'll notice that it will either come up with a message saying an update is available upon start up. Or the “client update available” option will be shown when you press the Menu softkey. There are some minor tweaks such as the map interface, but it's mostly the rebranding of Bing that is most prominent. You never know, maybe there will be a complete revamp of the software down the road?
