MobileGestalt Keys (De)obfuscation.

MGKeys

Mapping of the obfuscated keys (or questions) used by iOS's MobileGestalt to the de-obfuscated, easier-to-understand ones. To obfuscate a key, Apple calculates the base64 of MGCopyAnswer{theKey}, truncates the last two characters and calculates the MD5 from the resulting string.

It is our job to de-obfuscate them all.
