The data does not HAVE to be routed through Blackberry's system. If your provider can create a service book that would allow you to connect to the GPRS service, you can buy the cheapest data plan and still be able to connect to the Internet. The biggest limitation of the Blackberry is that you cannot manually edit the service books.
