My cell phone is not reading the memory card

After reading through the archives of related problems, I decided to try some of the suggestions. Here is what I did for my LG Shine...I checked the sd card on the computer to make sure all the data i transferred was on the card and it was. After that, I use the music player on the cell phone to load the music into my library and was able to listen to the music stored on the sd card.The music which was downloaded to the sd card will only play through the music player on the cell phone and for the ringtones I went to the website and made my ringtones. http://makeownringtone.com/ This is the fool proof way of making your favorite songs your ringtone. Follow the instructions giving and in under 3 mins you can make your ringtone. The ringtones have to be under 300kb and in the mp3 format. Its really simple and easy to use and downloaded them to my computer. Hint of advice: email it to yourself that way you can forward it to your friends and family. Might I remind you that its FREE!!!!
ENJOY ;-}
