T-Mobile subscribers waiting on pins and needles for the day their HTC Sensation 4G or Amaze 4G will get its Android 4.0 update don't have to sit so uncomfortably for much longer: the carrier has just narrowed down the timetables considerably. The first wave of owners will get its Ice Cream Sandwich just desserts on May 16th, when Sensation 4G owners can push Android 4.0.3 to their dual-core 2011 flagships. Amaze 4G users have a looser timeframe of the "coming weeks" to dig in. Either circumstance will see HTC slap on Sense 3.6 like it has with other pre-2012 device updates, so don't expect a full One S-like Sense 4.0 experience. Do, however, expect to pay an extra $15 per month for hotspot support on the Sensation 4G if you've been sharing your service on the cheap before -- it'll be required for sharing data with Android 4.0 and up.
