If you don't know what type of card you have, then just sending random  
APDUs to the
card won't do you much good, and you may wind up locking up the card  
and rendering
it useless.

In your example, you are looking at a Gemalto forum, do you think that  
your card is a
Gemalto card of some type?

Do a Google search for "OpenPlatform" or have a look at the OpenSC  
sources for
example to find more information on APDUs that you can use.

Well, why do you think that you need to do a SELECT FILE at first?  
Some cards don't
have any type of filesystem at all, so a SELECT FILE won't do anything  
with those types
of cards.
