Here is an interesting article on how Homeland Security can track you
via the E911 capabilities of your cellphone/network. Interesting how
T-mobile can track it without GPS even when phone is idle.
And unfortunately Qwest isn't going to die any time soon. In many
neighborhoods they already have fiber to the neighborhood box. Most
non-quest DSL providers are paying Qwest to use their network. I
would kill to have Utopia wired in my neighborhood.
