So the N900 is just for European, Australian, New Zealand, and Asian 900 MHz markets and TMobileUSA, based on frequency. Or its not AWS at all, and just a weird combination of frequencies. Or maybe Nokia has expanded the width of the radios to adress the problems of compatibility between UMTS I and IV.

Most european and asian 3G operators use 2100mhz UMTS:

There is no reason why the radios should not work in each market. They are tunable via software, and as long as the frequency is in the "band" of frequencies (ie the "2100" band, the "850" band, etc) it will work just fine since the antenna is of proper geometry to properly receive signals in that slice of spectrum.

I try to address a comment made by Christexaport as to the inter-workings of the 2100mhz band.
Now it's got me to thinking;
1) Can a knowledgeable person inform us of the differences between UMTS Band I and UMTS Band IV?
2) T-Mobile-U.S. does use both the 1700 and the 2100mhz bands for up and down 3G transmissions, correct?
3) Is the 2100mhz capability of the N900 compatible with both the U.S and the European/Asian protocols?
I would assume that the answer to #3 is "yes," but I would like a technical explanation.
770, N800, N810, N82
