There are a few different models of the BlackBerry 9000. The one that everyone sees prototypes of is the Bold, the exclusive model for AT&T set for launch in June. The version set for T-Mobile (likely available in August or September) will look slightly different, yet will work on their 3G network. They also DO own more 3G space than AT&T. AT&T, if you recall, only has 3G coverage in the immediate New York City area, whereas T-Mobile will eventually roll-out their 3G coverage outside the New York City area into Long Island and New Jersey (although it is currently only available in NYC).
