A Key

[MAFREI2003]

HI, I FOUND A VALID A-KEY (6 DIGITS) AND I TRIED ON A 6120, IT WORKS GREAT, I ALSO TRIED IN MANY CELLULARS, AND IT WORKED(DIFFERENT A-KEY FOR EACH CEL BASED ON THE ESN). I WOULD LIKE TO KNOW IF THE EEPROM OF A CELLULAR IS CRYPTO
BASED IN THIS A-KEY.BECAUSE THE WINEX HAS A ENCRYPTION/DECRYPTION BASED ONA A KEY
THANKYOU
