The T-Mobile HTC Sensation 4G is receiving an Android 4.0 update today, right on schedule, bringing an end to a six-month wait for users. Meanwhile, we'd heard previously that an Ice Cream Sandwich update for the HTC Amaze 4G was also on its way in "the coming weeks," and TmoNews has now given us a due date of May 21st. It's a good week to be a T-Mobile customer — today's update news comes after monday's announcement that a number of Samsung T-Mobile devices will be receiving Android 4.0 shortly.
