Haha yes. Just doing it for maximum resale value I guess. I think it has band 30 for AT&T over the model I have.
It does. Although no stock in store at the moment (I'm in Boston). I bought the day after launch, so tomorrow's the last day to return. However, I could potentially get a Samsung chip...I have TSMC right now. That would be awful.
I mean the one I have (same model for T-Mobile, Verizon, Sprint) supports all 3 and even AT&T, just not Band 30. That I think will be rolled out in the foreseeable future in congested cities to increase capacity.
