Using the wireless service provider's Internet gateway
Most wireless service providers provide an Internet gateway that offers direct TCP/IP connectivity to the Internet. Some wireless service providers also provide a WAP gateway that allows HTTP connections to occur over the WAP protocol. A BlackBerry® Java® Application can use either of these gateways to connect to the Internet. If your application is for BlackBerry device users who are on a specific wireless network, using the wireless service provider's Internet gateway can often yield good results. If your application is for BlackBerry device users on a variety of wireless networks, testing your application against the different Internet gateways and achieving a consistent and reliable experience can be challenging. You might find it useful to use the BlackBerry® Internet Service, and use the wireless service provider’s Internet gateway as a default connection type if the BlackBerry Internet Service is not available.
