About WTLS
The WAP Browser configuration is designed to use WTLS to encrypt data that your BlackBerry® device sends and receives over the Internet
through a WAP gateway. Communication between your device and the WAP gateway is encrypted using WTLS. Communication between the
WAP gateway and content servers is encrypted using TLS or SSL.
