TmoNews is reporting that some customers are having some luck getting T-Mobile to give them MyFaves for free. MyFaves is T-Mobiles plan that gives you free calls to 5 numbers of your choice. It usually costs $10 as an add-on and cannot be added to older grandfathered plans which annoys many.
From the reports coming back it looks like T-Mobile is offering the MyFaves feature free as part of their retention plan to keep customers. Many people are either just asking for it or saying they want to cancel and get it added. This is in no way a easy thing to do but if you have a bargain minded shopper attitude you may want to try it out.
