Thanks. I'm not going to just blindly enter the code into my cell phone
without doing some research because I am afraid of doing some damage I
can't undo. But I'll research the code and find out if and why it would
work on all phones and get back to you.
Here's what I've found so far.
Entering *#7465625# gives you the lock status.
Entering #7465625*638*# Disables network lock with password lock
relations in addition to the network. Apparently your password is 12415647.
Substituting *738* for *638* will relock the cell phone.
