I thought I had ordered a SDHC, but I got a 2gb sandisk mobile ultra....I still thought it would work with my R4 on its way. Well I get the loading screen that wont go away, is it because of my SD card? I have tried 2 firmwares for SDHC, and formated the card from FAT to FAT32? don't really no what else to do. Is it my SD card? Help?
