The original analysis that Cory Doctorow links to is here
Whilst we know Verizon don't install Carrier IQ it is not possible for them to collect this information without installing another brand of spyware:
And remember your "opt-out" only opts you out of them the data for specific purposes defined in the opt-out. It doesn't stop them using the data for other purposes.
It annoys me that people keep spouting this FUD, that if AT&T doesn't buy T-Mobile there are no other potential major bidders T-Mobile may break up and sell off assets piece-by-piece or shutdown completely.
Off the top of my head I can see multiple potential bidders for T-Mobile at the right price (not the AT&T "I am rebuilding my monopoly price").
For example it would make sense for both Telefónica (which already has a major presence in the Americas) or América Móvil (which also has a major presence in the Americas, with almost twice as many subscribers in Mexico as T-Mobile has in the United States. Both could find strong synergies in buying T-Mobile, up selling additional services to the Hispanic community.
Vodafone as well has long wanted to use their own brand in the United States (especially since they are only a minority shareholder in Verizon wireless). The could sell their Verizon Wireless stake and use the money to buy T-Mobile.
It could even make sense for China Telecom as they already plan to launch Wireless Service in the USA next year.
I am sure I am just scratching the surface of potential bidders so please, please stop the "OMG, T-Mobile will shut down if AT&T doesn't buy them" FUD.
