1) What are the potential problems I could experience if I move apps to my SD card? Do I lose them if I have to do a battery pull or anything like that? I ask because my D2 occasionally gets laggy and freezes up and I've had to pull the battery a few times. 2) I have downloaded a bunch of soundboards to get ringtones and notification sounds. Can I uninstall those soundboards once I've saved the sounds or will the sounds I've saved go away too? 3) If I finally get pissed enough to do a factory reset will it erase whatever I have on my SD card or is there some way to save my songs/pics/settings? Can I copy it all to my computer and then put them back after the reset? Thanks for any help you can give.
