BlackBerry:

Problem:
I am provisioned for data on my Blackberry but I do not have a web browser on my device.

Solution:
The browser should be installed on a device once it is provisioned with the carrier.  If your device does not have a web browser then from the device, navigate to

Settings -> Advanced Settings -> Host Routing Table

Select Menu and choose Register Now

This should bring down the Blackberry Internet Browsing service book from the carrier and load the browser onto the device.  If doing this still does not load the browser then the next step is to contact your carrier for assistance.
