Power up and run the 'GetSPC(PPC 2003)' executable on your device. In the 'Input' field, enter the ESN number you wrote down but be sure to use ALL CAPITOLS for the alpha values.

When navigating a file system via a user interface, graphical icons representing ZIP files often appear as a document or other object prominently featuring a zipper.
