Microsoft Suggests Blocking iOS 6.1 Over Exchange Bug

Apple’s iOS 6.1 update may have solved an issue that undermined cellular performance on the iPhone 4S, but evidently it didn’t repair a second bug that cut some users off from Microsoft Exchange. On Tuesday, Microsoft broadcast a support document acknowledging the issue and offering some workarounds to avoid it that range from throttling iOS 6.1 devices to blocking them entirely. Microsoft is currently working with Apple to fix the problem.
