If you use the my faves on the mt3g slide, and you don't have myfaves on your plan, does that add myfaves to your plan? or is this only on there for the grandfathered my faves plans. I hope that made sense. Let me try again. Ok on the slide, there is a "My Faves" app that is build into the phone. It basically lets you add I think 10 people, if I use that app and add 10 people, even though I don't have myfaves on my plan, do I get charged extra?
