This week Apple has acknowledged two bugs in iOS 6.1.

First, accepting an exception to a recurring calendar event may cause excessive Exchange server activity. Says Apple:

Apple has identified a fix and will make it available in an upcoming software update. In the meantime, you can avoid this bug by not responding to an exception to a recurring event on your iOS device. If you do experience the symptoms described above, disable then reenable the Exchange calendar on your iOS device

The second bug allows access to parts of the iPad or iPhone even when the device is locked. Note that the hack described allows access only to the device's contacts, photos, and voicemail. Apple Data Protection is not broken, so data remains encrypted.

These issues are also present in the 6.1.1 update for the iPhone 4S.
