Hot on the heels of the release of iOS 4.3, Apple has also pushed out iPhone Configuration Utility 3.3 for Mac OS X and Windows. The utility helps system administrators to deploy iOS devices in enterprise settings.
iPhone Configuration Utility lets you easily create, maintain, encrypt, and install configuration profiles, track and install provisioning profiles and authorized applications, and capture device information including console logs.
Configuration profiles are XML files that contain device security policies, VPN configuration information, Wi-Fi settings, APN settings, Exchange account settings, mail settings, and certificates that permit iPhone and iPod touch to work with your enterprise systems.
The update presumably makes changes and additions to support devices running iOS 4.3.
The Mac version weighs in at 11.46 MB and requires Mac OS X 10.6, while the Windows version weighs in at 36.43 MB and requires Windows 7, Vista SP1, or XP SP3, along with .NET 3.5 SP1.
