I find it odd that people are having mixed results with this. We should have someone start a count of what brands of cards people have gotten to work with the hack and what brands people have NOT been able to get working, as well as where they got them. I'm not really sure how to do that, but here is my information, and I WAS able to get my card to work.

Kingston class 4 Microsdhc 4 gb card - got if from newegg:
Newegg.com - Kingston 4GB MicroSDHC Flash Card Model SDC4/4GB - Retail

I wonder if the "class" matters. I saw on this newegg page that there were some class 6 devices out there, and noticed the one I got was a class 4. Maybe there is something with that causing problems for people.
