Don't Like Bing? Google Search App Is In The Marketplace

"Searching with Google on your Windows Phone 7 device just got easier. The Google Search app for Windows Phone 7 provides quick and convenient access to a rich set of search results, allowing you to search the web, images, local, news, and more...This initial release of the Google Search app includes several features that help you to search faster - suggestions appear automatically as you type, you can choose to repeat a query from your search history, and your current location is used to provide more relevant results."

Windows Phone 7 incorporates Microsoft's Bing search engine into the OS, but if you prefer the results you get from Google, then this app is for you. You're not going to get the level of integration in the OS that Bing has, but choice is good right?
