Remember the Ice Cream Sandwich update for the HTC Sensation 4G that we told you about yesterday? Turns out that it does more than just bring ICS - it also kills free tethering.
Wait, what? T-Mobile had free tethering? Technically, no. But in reality, yes. Here's how it used to work: T-Mobile offered a tethering service for around $15 per month. Somehow, though, there was a "technical limitation" that actually prevented them from charging for the service on Android devices (though Verizon, Sprint, and AT&T have never had a problem taking our money for the same thing). With the Ice Cream Sandwich update, however, they finally figured out how to put the nail in that coffin, so users who want to continue using the tethering service will have to start actually paying for it post-update.
