T-Mobile is extending is Content Lock filtering mechanism to the BlackBerry. Content Lock is designed to prevent consumers -- particularly children -- from accessing adult content as well as unmoderated chatrooms, gambling sites and the like via T-Mobile's service. You don't have to be too wily to circumvent the filter -- which is automatically set to "on" on all T-Mobile accounts -- as the device alerts you when content is being blocked.
