Just my own personal experience, but I question if you installed the SD Card properly. I'm reasonably tech savvy and I pulled my SD card and put it in my new phone and the same thing happen, apps grayed out (because the portion on the SD card is not found, though the app is found on the memory card on the phone), no SD data. It turned out I'd installed it just a little off the pins. Test the card using a PC adapter (USB or SD adapter, both available from Radio Shack for under $15) to verify the data's there. If it is, then you need to try the install again, but shine a flashlight in the phone slot and make sure you know where to line up the micro SD card; it's a precision fit and missing by a hair is no good. I was surprised that the slot wouldn't force the right fit, but apparently, it didn't.
