In order to use a 4 gig card, you have to be using Beta versions of th software and firmware. If you'd like to do that, go to: www.aph.org/beta Otherwise, if you're more of a patient soul, then 2 gig is the limit for now. You will be able to update your Book Port, once it is released to everyone, which shouldn't be too much longer. .

I would probably want to save everything so I figure having the largest card I can would be better for me. I thought that I heard that after a certain upgrade with the software, us users would be able to use the 4 gig card. Is this true? Is it still the cf type 1? Andy.
