I was using a microSDHC with 4GB when I was checking out the Pandora today, but for some reason the device stopped recognizing it at a random point when I re-inserted it, it's now shown as (unrecognized symbol)PNG(unrecognized symbol) and inaccessible. I've since flashed the firmware from the support page with another 2GB SD card because there was a firmware which was missing the browser and other features on it by default, but the SDHC card is again not recognized anymore. It works flawlessly with my PC, as before. I hope someone can make suggestions as to how to fix this, as I don't really have any other SD cards available at the moment.
