Bing Maps offers an iOS SDK to develop applications in Objective C within Xcode. Users can note that the iOS map control is supported by Bing's road. It offers aerial and hybrid map styles. It can also access a user's location as long as the phone's GPS is on. What makes this kit valuable is its capacity to use the Bing Maps REST Service that includes geocoding and routing to build a mapping application. This idea serves to help coordinate the Bing Maps Control with Bing Maps services. Besides using the iOS SDK, developers are invited to use the Bing Maps SDK for Windows Phone and the SDK for Android. These services might provide a more complete development experience to create apps associated with geocoding, routing, and mapping services.
It's a little bit creepy, but it's also a little bit genius. Singles for Foursquare builds a dating and messaging service on top of the location-sharing application. The result is a mashup that could match up hip iPhone-using, Foursquare-playing, same-bar-going early adopters.
Facebook is taking another big reach toward location sharing with its latest update to its Places API. When the platform launched in August, we wrote that it was "read only for now." Now all developers can, with users' permission, share their locations on Facebook. And, perhaps more exciting, Facebook has opened up its venue database to help out.
