I have used 2 different 2GB cards, one works with a reader that it came with, 
the other won't work with the reader the other card came with, I did not try the 
switch the other way, but it appears that the cheap readers included with the 
cards are not interchangeable as they cut too many corners in the testing to 
make them nice and cheap.
