We covered an app a week ago that filled in a big hole in the Windows Phone OS, specifically you can't save Bing searches to the People Hub. This inability is quite inconvenient as it means you have to manually copy information to your contacts, which if you have a few restaurants to add, can take some time.
Now, Add to Contacts, a different and in many ways a better app, is available from the developer of "I'm a WP7!" meaning you expect quality from the design and implementation. Very Metro-influenced, the app is fast and has great options including the ability to save photos where available.
"With Add to Contacts, the entire process is automated for you, including retrieving an image for your Contact if it’s available!
PRIMARY USE: Go to Bing Search, get local or Local Scout results, go to the apps tab, then tap 'Add to Contacts'!
SECONDARY USE: Search for local results from within the app itself and add them directly to your contacts!
The app provides integrated Local and Nearby search, with the ability so save your most recent search, but the real power comes from tapping Add to Contacts right from your search result profile!"
The app fetches for $0.99 with a free trial. If you need this feature then we have to give a recommendation for this app as it does its job quite admirably. Pick it up here in the Marketplace.
