Verizon was the first to require a data plan with BlackBerrys. Sprint expanded the idea by requiring certain phones to have specific plans that included data. AT&T did this with the iPhone and has expanded it to other devices much like Sprint. T-Mobile has been the most lax with this and with data caps (fair use) and may still allow a BB without a plan, but I'm not sure.
