Nokia 3100 is missing from the auto unlocker

Hi,
I wanted to unlock my brother cellphone with the auto unlock code generator.
it worked well with my 6100 phone,
but when i searched for the 3100 phone i was surprised to see that it missing from the phone list!.
is it deliberated?
can i unlock my brother cell phone to get free from the chains of my cellphone company?

Thanks,
Roi.

Just select 3200. Its the same type (Asic 2). That will work fine
