Just an FYI:  That the new OS releases for WM5 and WM6 for MC35 set the default SD operation mode to SDMMC (with no remove on resume checked).  We have recently done the same on MC70 OS releases.  This assures the best operation of SD card read/write during the suspend and resume process.  If you need to utilize an SDIO card such as an SDIO scanner or RFID card, you will need to set the operation mode to SDIO through the SD Switch utility on the device.
