sgh-d407? Okay so is there a certain amount of time it needs to be? Also when i go into sound settings > incoming call> it says default sounds, downloaded sounds, and favorite sounds. so mine is a favorite sound i click on it then it says NOT ALLOWED! and i don't have the cord so i can't download a file onto my phone but the strange thing is is that is has the option for a favorite sound. any advice? btw it is from the cingular line a samsung phone model number sgh-d407.
