I only know about the US phone market but if the leak is correct and it is on T-mobiles US 3g bands then it would make a lot of sense. The N97, Palm Pre, iphone and many other high end all in one phones will not work on T-mobile 3g here. T-mobile would have customers switching carriers just to get this phone, just like people switch carriers to get the iphone etc. It would make T-mobile much more competitive.

Or you could buy it unlocked for the premium prices these other phones go for unlocked
