T-Mobile has announced that their HTC Sensation and Amaze 4G both will get ICS. Unfortunately, both of the devices are tacked with big To Be Determined (TBD) schedules, so we’re not too sure when the updates will hit. Still, the carrier has acknowledged Google’s fancy new OS is coming, leading us to believe the requisite behind-the-scenes testing is currently underway. Unfortunately, the carrier doesn’t offer any ETA for either of these updates, but promises to update its users once more information is available.
