Manually download the HTC EVO 4G Gingerbread update - HTC Source
The Gingerbread update for the HTC EVO 4G is finally available! Sprint will start pushing out the Android 2.3.3 update to the EVO on June 6th, but you can now manually trigger the update on your own. Simply press Menu > Settings > System Updates > HTC Software Update > Check Now > OK > Yes and you should be good to go. Reports indicate that the official Gingerbread update for the HTC EVO 4G is just over 110 MB and will update your build number of your phone to build 4.22.651.2. If you download the update over Wi-Fi or 4G you should be able to complete the entire update process in less than 20 minutes.
The Android 2.3.3 update for the EVO will not include any of the new HTC Sense 2.5 feature found on the HTC Inspire 4G or HTC Thunderbolt, but that’s certainly not a surprise since we didn’t see any of those feature roll out to the HTC Desire when it received its Gingerbread update a while back.
Be sure to share your thought about the new update and let us know if you run in to any issues.
