The recent release of iOS 6.1 exposed an issue with DPS viewers that have in-app purchasing enabled. This issue causes the viewer to crash when a network connection is not available. This includes situations where Wi-Fi or cellular network connections are not available, or when the device is in airplane mode. All viewers built with release 24 and earlier of the DPS tools are affected and will crash when a network connection is not available. Release 25 viewers are unaffected. Single Edition applications, regardless of release, are unaffected.
We have released a hotfix, now available through DPS App Builder, to resolve this in release 24 viewers. Customers who have live apps in the app store with release 24 or earlier should re-build their applications to release 24 or 25 with DPS App Builder and re-submit the viewer to Apple for approval.
