okay... I was googling it and found things that indicated tmobile might use both 1700 and 2100 in different areas... but it seems AT&T uses 1900, so if any of that is right then you *may* be able to use t-mobile 3G in some areas, but that's not really good enough. Probably not a deal breaker for me, but it's good to know most overseas countries use 2100. I sure wish everyone could agree on a smaller set of frequencies. This phone supports the most I have ever seen yet it still doesn't get them all.
