Microsoft has added another SDK for Bings Maps - this one is for iOS and provides a set of Objective C classes to develop iPhone and iPad applications within Xcode, plus documentation and several sample projects.
The iOS map control supports Bing's road, aerial and hybrid aerial map styles, and includes the ability to add pushpins to the maps and access the user's location via the GPS to locate the phone on the map.
Microsoft has separated the Bing Maps Controls from the maps service to help increase performance across the platform. That means developers will be able to use the iOS Control, like the WP7 and Android ones, with the Bing Maps REST service to create a mobile map application.
Developers can integrate Bing Maps into mobile applications for free and the Bing blog comments:
