didnt the latest R4 kernel update allow use of the high capacity cards (4gb+)?
Anyway i'm loving my R4 even more now after i softmodded my Nintendo Wi-fi Adaptor as its a rebranded Buffalo soft AP with custom software by Nintendo, it works like a normal AP now (access point) thus allowing me to use the homebrew apps, namely Be up and DSOrganize and its IRC client, had a poke around in DSorganizes online homebrew thing, pretty neat, downloaded a few things, though for some reason i download at a max of 5kbs :S at least in DSOrganize anyway, not sure about web browsing but that seems pretty darn slow as well
