Originally, we were supposed to see an official Gingerbread update come to the HTC Thunderbolt in the second quarter. That possibility is now gone, but according to an HTC rep statement, users have been given the "go ahead" to spread the word of an impending release of the Android 2.3 OS during Quarter 3. This gives them about an 8 week window. Here is the quote from the HTC rep,
Is it just me, or does it seem like smartphones are getting a bit like PC video games? They release the game or phone to early, then "patch" things later... I realize that an updated Android OS isn't quite the same thing, but they sure have dragged their feet on getting it to us. Better late than never, I suppose...…We will certainly pass along your concerns to the developers at HTC. We are working hard to address the issues you have mentioned with future updates for the device. We are excited to announce that the HTC Thunderbolt will receive the Gingerbread (Android 2.3) update in Q3 2011. Stay tuned for details as we get closer to the update availability…
