I know this was already mentioned in the faq, but I'd still like a second opinion. I own a R4DS , the original; no clone. Now, I'm aware that the R4 only supports MicroSD and not MicroSDHC. Also , some people here have mentioned that R4 is capable of supporting cards upto 4GB in size. So, I went to purchase a 4GB card...but it said 4GB MicroSDHC. I checked out another memory card, and it said the same.. 4GB MicroSDHC. Will the above mentioned cards work in my R4? I'm concerned about the MicroSDHC part in particular, since the R4 doesn't support it. But I haven't seen a single memory card that says 4GB MicroSD.
