This is an email I received from Sprint. I can only assume all major cell phone providers have a similar policy in place at this time. As for me, I don't want Sprint tracking my usage.. even if it is supposed to be anonymous. Its one thing to track usage to determine problems with their network but there is no reason to track what websites I am browsing.
To change these settings in Sprint, you have to log in, click on my preferences and then click "Manage mobile advertising and reporting preferences" then change the settings for each phone in your account. Oh, and make sure you use Internet Explorer because even though the rest of the site works fine in Firefox, this one particular link will only load in Internet Explorer. wtf.
