T-Mobile USA announced today that they have surpassed 25 million customers. The significant increase in customers was due to the successful launch of the T-Mobile MDA and SDA in February of 2006, the Sidekick 3 in July, the BlackBerry Pearl in September, and Dash in October.

Although the nation’s largest wireless carrier, Cingular, recently announced having over 60 million subscribers, T-Mobile, the smallest wireless carrier, is adding customers at a fast rate.
