However, there’s a little more new on an Android 2.3 Gingerbread update concerning two smartphones, the HTC Thunderbolt and HTC EVO 4G, which according to an article over on Technobuffalo, an by way of Unwired View.

According to Unwired View a reply to a person’s inquiry over on Talk Droid, about the when Gingerbread update would be released, HTC responded with both the HTC Thunderbolt and HTC EVO 4G will receive the update before the end of June baring any major setbacks.

Here’s what the HTC reply said…” I’m happy to inform you that both the Evo and the Thunderbolt are definitely on our list to receive the 2.3 Android OS update. At this time, we don’t have an exact launch date, nor are we. However, we estimate that it will be available in the second quarter of 2011 (anywhere from the beginning of April, to the end of June), assuming that there are no major setbacks. Once we have a better idea of when this update will be available for your phone, we’ll be sure to announce it.”

So there it is, if you own the HTC Thunderbolt, or HTC EVO 4G look towards the end of June if not before for Android 2.3 Gingerbread to hit your smartphone.
