This is one of my big questions. My owner's manual (good only for squashing bugs, really) stops after telling you where the SD card is. Does anyone know if the X3/X30 can use SDHC? SDHC is not backwards compatible with original SD.
I've read that the X30 can use up to 2GB SD cards and mine works fine with them. I've tried 4GB cards and they do NOT work so I'll assume 2GBs is the limit since I've never seen a 3GB card.
