How a device protects a connection to a

WAP gateway

BlackBerry Device Software versions 3.2 SP1 and later supports WTLS, which is designed to provide additional security

when a BlackBerry device connects to a WAP gateway. A device can connect to a WAP gateway to access services that are

provided by your organization's wireless service provider or to access a web site. WTLS encrypts and decrypts information,

authenticates users, and provides data integrity.

For more information about WAP gateways, see your organization’s wireless service provider.
