Apple’s Configurator tool allows you to configure and deploy up to 30 iOS devices at a time. The free app allows you to configure settings like Wi-fi and Exchange ActiveSync, and well as restrict access to features like the webcam and even internet browsing.

Someone in my school has been using Configurator with a Datamation Systems 49-port USB hub with a mix of iPods, iPads and iPhones. It seems to work with more than the 30 Apple specifies.
They told me Configurator doing IOS updates only handles 10 devices at a time but then moves on to the next ones on the list recognized. This saves a lot of time.
Does anyone else have any experience with this?
