Ordered my new GS4 a few days ago and waiting for it to arrive. I have a 32gb SD in my current phone (Droid X) and was thinking about just using it in the new phone. However after doing some reading through the various forums I have noticed some have recommended getting an entirely new SD card. I don't mind doing that and spending the extra money, but is it really worth it? I don't want to transfer anything unnecessary to the new phone from the older SD card. Any info or suggestions would be appreciated. Thanks for your time.
