Yeah...about that... We're working on it, I promise! I have the app on my phone now for internal testing, so it really can't be too long before it becomes available for everyone else too! (Sorry for the vague, non-time-committal statements!)
Yes be cautious with Best Buy. They are constantly mos-pricing and misrepresenting information to get you realed in. Then you are disappointed when you go there and the price or specs are wrong. Happened to me on at least 4 different occasions.
