question about remote unlocker

[anybody]

I have a question about remote unlockers

Do they actually send something to the servers?? or do they just connect to the server to check the username and password for unlocking a T68 for instance?

Don't they read the NCK code directly form the eeprom???
then why doesn't anybody try to crack the remote unlocker so that it doesn't connect to the server and give you the codes immediately??

Because this Terminator software sucks and it "kills" phones. Plus it is dongle protected blah blah blah. . .

Remote unlocker on the other hand never kills phones and all it requires is a serial cable.

yes they connect to the server

first because u need emma II card (original or emulated) to boot the phone and get ID and codes

seccond because the codes come from there

u can't crack'it
