Extract Kc from Phone?

[MATTHEW EVANS]

Thanks for the advice all. I purchased a cheap sim reader and used xsim to 
retrieve the Kc. Funny thing is the 3310 doesn't seem to delete the Kc file if I 
power down normally. Even funnier is the fact that the Kc doesn't change even 
after power cycle! I guess the Kc change policy must be specific to the 
operator. It will be interesting to see how often it gets changed! Probably not 
that often :).

Matt.
