Samsung Galaxy S Vibrant handset. I have set up Social Hub for my Facebook and Twitter accounts, and tried to setup Yahoo mail. I do now receive Social Hub notifications of incoming Yahoo emails, but I do not see the Yahoo email icon in my Social Hub accounts list that now includes Facebook & Twitter. I also do not seem to have the ability to select my inbox as a 'sync-able' folder. Only the bulk folder appears to be sync-able. Must I upgrade to Yahoo Mail Plus, and its POP support, for Social Hub to work correctly for Yahoo mail? I have already downloaded the Yahoo android app and that works fine, so I don't plan to upgrade just for Social Hub features.
