The OTA (Over-The-Air) Android 2.3.3 (Gingerbread) of HTC Incredible S smartphone has been made available to Malaysia today (26 May 2011) morning.
You can manually check for the update now, or wait for the automated update alert appear on your HTC Incredible S smartphone sooner or later.
Although this update will not cause any data or setting lost to your smartphone, it is always a wise choice to perform a backup using tools such as MyBackup (or the paid MyBackupPro) or Titanium Backup (or the paid Titanium Backup Pro) prior to the update, just in case...
Before the update, my HTC Incredible S is running on Android 2.2.1 (Froyo) software number 1.38.707.1.
After the update, it is now running on Android 2.3.3 (Gingerbread) software number 2.12.707.5 with HTC Sense 2.1 (sadly, not the newer 3.0 yet).
Manual update is pretty easy. Just go to Settings > About phone > Software updates and click on the "Check now" button. You should be able to get the update notification as below.
After the download, you'll come to a confirmation screen to apply the update to your phone.
If you answer OK to Install now, your phone will be rebooted and the update process will begin. It takes a while to complete. Then the phone will reboot again, and your phone is now powered with Android Gingerbread!
