Im brand new to this android stuff, ive had BBs for years. I baught this mytouch 3g from this guy today and put my sd and sim in it. no problems. worked instantly. figured out how to go look at my media and play with my camera and it said please insert sd card. botton line. its formated. hell i formated it on my bb. ive formated in my mytouch, all it ever says is its blank or unsuported file system and it simply shows up as being there but not useable. avaialble data is not available ect ect. I cant use my damn sd card. but i was working just fine in my bb and i can even access it thru my black berry, i even tried usb mount and it still said i dont have a valid sd inside. wtf? any noob help? this better be a noob problem not an issue with the phone.
