There's no more room for vague estimates anymore, since more and more manufacturers already started rolling out this much desired update. HTC realized this, and decided to announce an official list of handsets which will be lucky enough to enjoy the Android 4.0 ICS goodies.
The list goes as follows: HTC Amaze 4G, HTC Desire SHTC, Desire HD, HTC EVO 3D, HTC EVO Design 4G, HTC Incredible S, HTC Sensation, HTC Sensation XL, HTC Sensation 4G, HTC Sensation XE, HTC Raider, HTC Rezound, HTC Rhyme, HTC Thunderbolt, HTC Vivid.
There already are certain regions in which the update for the Sensation and Sensation XE has started rolling out, with other markets set to follow in the coming weeks. Also, the update for the Sensation 4G and Sensation XL, as well as the rest of the above-mentioned handsets should be updated within the following weeks.
It's true that HTC could have done a better job when providing a time frame, but if you have one of these handsets, at least you can sleep well at night, considering that sooner or later, your turn will come.
