In terms of freedom, T-Mobile was the only large carrier to oppose warrant-less wiretapping of Americans. In terms of cost, T-Mobile offered the best non-contract prices, and I could use my Nexus One or iPhone on their network for a reasonable price.
Me too, the even more plus plans from T-Mobile are great and most likely exist because of the parent company. T-Mobile also has great customer service and is my favorite US cellular provider. AT&T is worse in nearly every way except coverage area and now we'll have even less competition in the US, where prices are already too high.
Did they accidentally release this 12 days ahead of schedule?
