A few hours ago HTC announced it is already testing the Gingerbread for the original Desire and will start the QA procedures this week. Obviously the update is nearing release and the wait will be over soon.
Initially HTC promised a Gingerbread update for the Desire, but then it was dropped due to incapable hardware. After the massive pressure it got from users the company made another U-turn and decided to launch the update anyway, even if it will compromise a feature or two.
And here we are today when HTC is almost ready with the update. Here is the HTC's statement:
We suppose we'll see the Android 2.3 update soon after the QA is over. So arm up with just a little more patience and prepare for an update.
