The iPhone is also getting a face lift that should aid in its usability in the workplace. New features will include Microsoft Exchange support, "push-based" email, contact and calendar synchronization, additional support for VPN's, etc. These new features and the release of the iPhone SDK will undoubtedly make the iPhone a worthy competitor to the Blackberry in the workplace.
