Sorry if you're not taking these anymore, or I'm posting this in the wrong forum, but I thought I'd post a compatibility test for my SDHC.
User: yoshicircuit
Card Type: SDHC class 6
Card Size: 4GB
Card Manufacturer: Verbatim
Twilight Hack: Didn't try
Homebrew Channel: No, apps wouldn't load
I am certain this specific SD Card has not yet been posted on the
Compatibility Test page.
