Best Buy gets quite a few early exclusives, the white Evo was one of them. The Incredible was on Verizon, so my bet is that the Incredible S will be on Verizon as well.
I am rather disappointed in that device, it's really just a marginal upgrade over the original.
The specs show it as GSM/WCDMA I have heard that Wcdma is not regular CDMA but a form of GSM, and then I have heard it is, IDK what to believe. But if it is on VZW it sounds to me that it could possibly be a world phone. But as of now they are saying it is Europeon phone.
