Like the metric system? But I believe Fargus is right to the point with this one, these frequencies have been set as standards around the world to make life easier for consumers, I feel like it's only appropriate that they not waste extra money to customize it for a select few countries out of many. That said, I do understand the AT&T dilemma because they are beautiful when it comes to voice coverage but anyone could have foreseen this problem a long time ago when they decided to stick with the 850 frequency route. You win some and you lose some...in the case of the N900, AT&T loses it's 3G compatibility since Nokia just didn't want to spend the extra cash.
