Ray Walters of Android Guys puts into words exactly how I feel about T-Mobile and Samsung not releasing an over the air update of Froyo on the Samsung Vibrant. As said in my comment of that post,
I think the most important part of this article is that they dangled the update in front of us. In fact it was once a selling point in the beginning. That is immoral and unethical. And I'm sure Ray himself would say that was the catalyst to the whole situation.
