While the algorithms for computing unlock codes from the
IMEI of a
GSM
phone seems to be an open secret, all I've ever heard in various forums
is that the MSL on
CDMA phones is truly a random number, and the
techniques for unlocking them do not involve computing the locking code
from the
ESN. Either the code is "social engineered" from of the
provider who has it, or some major hacking on the phone's firmware is
done to bypass the lock. The standard flashing tools from, say,
Motorola, won't update the the firmware on an MSL-locked phone, so those
programs have to be, ummm..., enhanced with that ability.
