I Phone Dev

The document discusses creating on-demand enterprise applications for the iPhone using the Force Platform. It outlines three approaches: using Visualforce for web-based apps, using Force Platform Mobile for easier native apps that leverage the full Force Platform, or using the iPhone SDK and Force SOAP API for native apps with full SDK features but requiring a connection. Force Platform Mobile is described as the quickest way to create a native app while Visualforce is best for quick prototyping and the iPhone SDK provides the most UI options but requires connectivity.
