ArcGIS for iPhone extends the reach of your GIS from the office to the mobile web. It includes a free application that you can download from the iTunes App Store along with a native Objective C/Cocoa developer kit that you can leverage to build your own iPhone applications.

ArcGIS API for iPhone has now been made available for download as part of a public beta. The ArcGIS API for iPhone enables you to build iPhone applications that utilize the powerful mapping, geocoding, geoprocessing, and custom capabilities provided by ArcGIS Server.

What can you do with the iPhone API?

Using the iPhone API you can:

• Display and use maps that blend dynamic and cached (tiled) map services from ArcGIS Online and/or your ArcGIS Server.

• Execute sophisticated geoprocessing tasks and display their results.

• Search and identify features and create useful reports of feature found.

• Collect locations by sketching on the map or using the GPS embedded in your device
