So, I need a larger SD card. I want to have a couple vids and lots of music on my phone at all times. Speed is a plus for transfering large files on and off my phone. Does anyone know if class 10 sd cards are comaptible withe these phones? I figure why not get a class 10 over a class 6 if it works fine. Otherwise I can settle for less if compatibility is an issue. Also, I would like to go 32GB. Does anyone know of or have experience with class 10 sd cards in the Centura. Thanks for any input.
