Is it possible to move apps to the SD card with this phone? I only see two options for apps that I *know* support being moved to the SD card: "move to phone" or "move to internal memory." I also know internal memory is NOT the SD card, it's part of the 8gb that comes with the phone. Does the phone need to be rooted in order to move apps to the SD, or is it just flat out impossible with this phone? If it was, that'd be a real bummer.
