Due to changes made by Apple recently to some of the files you need to download for setting up provisioning and code signing for iOS devices, people just starting or who have recently added a device or renewed an expired certificate may run into issues or receive errors such as "Data written is smaller than expected, unable to finish signing process" during the process.
The fix for this is to use the iPhonePackager.exe application from the August 2011 UDK. If you have upgraded to the August 2011 UDK already or plan to, you don't need to do anything additional as that will solve the issue. If you are using an older build and wish to continue using it, you can download the August 2011 UDK, install it, and copy the iPhonePackager.exe file in its Binaries directory to your UDK version's Binaries directory, overwriting the old version.
This new version will work with older provisioning files as well so there is no need to download new files.
