OK, I went to CompUSA yesterday for work. While waiting on the guy to locate all the crap I needed from the warehouse, I went to the handheld counter. I asked the guy how the SDIO mem cards worked and he said "I dunno, let's find out." So he popped open a case, takes out a card, and hands it to me. Turns out it is only storage space in my case. I go to take it out and pass it back and he says "Keep it". Woo Hoo! Free memory.
