Hi

Can someone clarify why this would be used 

 /* iOS BLUE LINKS */
    .appleBody a {color:#68440a; text-decoration: none;}
    .appleFooter a {color:#999999; text-decoration: none;}

instead of

/* Litmus Blue Link Fix */
    .appleLinksWhite a {color: #ffffff !important; text-decoration: underline;} 
    .appleLinksBlack a {color: #000000 !important; text-decoration: none;}

I am seeing the appleBody and appleFooter used in a lot of discusiions on coding for emails without any explaination. But the Litmus blog still contains the latter, I just want to understand the difference.

Thanks
