A bit earlier i tried sending a photo to a friend and it said it failed, now everytime I send a message it doesn't send it. it isn't in my sent messages either. (no message pops up btw) I've tried deleting my inbox and outbox, if switched on and off a few times and taken the battery out but it still wont send a message. all it does after i press send and it quickly backs out to the menu with no sending message icon in the corner!! plz help me
