It seems that several HTC EVO 3D owners on Sprint have gotten their long-awaited Android 4.0 Ice Cream Sandwich update ahead of schedule. This rare occurrence will no doubt please those who weren’t exactly expecting to get the OTA ICS update until early August.

The ICS update for Sprint’s HTC EVO 3D comes with some expected features of the not-so-new OS, such as a refined user interface, Face Unlock, redesigned camera app, compatibility with Chrome browser, improved keyboard app and spell checker, enhanced Gmail app, and Google+ integration. The update will also upgrade the Sense UI on your HTC EVO 3D to version 3.6.

As for HTC EVO Design 4G owners, we don’t think the ICS update for your model has been sent out – mainly because we have yet to hear happy words from users. But we expect it will come out sooner, rather than later – since the EVO 4G was placed on the same ICS upgrade timeline as its 3D cousin.

Lucky HTC EVO 3D owners, how do you like the new look and functions of Ice Cream Sandwich? Or are you still waiting anxiously for the OTA update to reach your phone?
