[Windows Phone 7 Development and Hacking] Heathcliff74:
Encrypted files are from an HTC ROM dump. On the device they are in the \Windows folder. There are files for each operator (worldwide). The attached files are for A1 Austria.

The .dbz files are simple zip-formatted files with a password. I don't know the password, but I used CSDecoder.dll from the HTC Connection Setup package to decode the files (call the decode functions directly).

This is the decoded content of the files:
