I think it can be a more general then that. The cards that are supported would be any standards compliant card, and the adress space would be limited by what the kernel supports. The SD card association has limtied the size of sdhc to 32gb, the max size of a fat32 system. The kernel can support disks this large as can the mmc card driver. No doubt there's a lot of crappy SD cards out there that don't comply well to standard interfaces though, but unless you're really really skimping there's likely nothing to worry about with any common microsd cards. You could even support larger cards because we aren't limited to fat32 on a linux phone. But has anybody found an SD card that doesn't work with existing hardware?? I only wish I had hardware so I can't test the few cards I have.. Matt

Or perhaps if 8GB in particular has been tested. It would be nice to know exactly what is supported, as those 8GB cards are getting cheap lately. We might have to wait for the first phones to ship to know for sure what will or will not work. Right now, only the OM dev team at FIC could test it for sure, and they are kind of busy getting mass production going. I think I'd rather have them do that and test the microSD size limits later.
