Apple – iPhone OS4 update – for Exchange

Apple will release a new update to iOS 4 at some point that will resolve this.  Please apply the following workaround until Apple releases an update.

Apple has published an Apple KB article ( with a link to a configuration file that can be downloaded to the iOS 4 devices via e-mail or with the Safari browser on the iPhone/iPad.  This configuration file will raise the timeout value from 30 seconds to 4 minutes.  The file is a basic XML file that can be edited using a text editor if needed.  The default value is 4 minutes, but can be raised in circumstances where 4 minutes is not enough.  Note: 4 minutes is enough for the vast majority of customers.
