For people without data plans, the t-zones item is not desired on the home screen. Removing it, or for that matter, any item from the home screen follows from our previous tutorials.
Goto HKLM/Software/Microsoft/ and click on CHome. Notice the Plugins string value, a list of items separated by semicolon. These items are what appears on the home screen. To remove t-zones, remove CLinks from the list. To remove anything else (for e.g. Photos), remove the corresponding entry (CMyPhotos for Photos).
