After the several leaked Froyo updates for the Samsung I9000 Galaxy S we can finally welcome the first supplied via the Samsung KIES desktop software. Meanwhile, the company announced it's sold over a million units of the various Galaxy S incarnations on the US market in less than two months.

The Samsung Galaxy S is known under one too many names in the US. AT&T customers know it as the Samsung i897 Captivate, T-Mobile calls it the Samsung Vibrant, while Sprint is about to sell it as the QWERTY-fied Samsung Epic 4G. As for Verizon, it's launching its Galaxy S version as the Samsung Fascinate in September.

Save for the different names (and the Epic 4G side-slide QWERTY keyboard) under the hood they are all the same (almost). All of them feature 4-inch Super AMOLED touchscreens on the front, 5MP autofocus cameras with 720p HD video at 30fps on the back and 802.11n Wi-Fi, Bluetooth 3.0, GPS, and Android 2.1 in-between.

And together they have been sold in over one million copies across the country. This happens less than two months after their launch in the USA and after the Samsung Galaxy S reached one-million-sales milestone outside the US.

As for the Android 2.2 update, its not the first official Froyo update for the Galaxy S we see but it's the only one (so far) that comes directly through the company's Kies software. We went ahead and installed the new firmware (version I9000XXJPC) and so far we're pleased with it. It still needs some final touches - we experienced some occasional freezes and lags (nothing major, though).

If you want to feed your Galaxy S some Froyo, just follow the guide found over at the XDA developers forum. In order to download the firmware you should set Kies in the so-called test mode via a Windows registry tweak as described in the post. Make sure you read the instructions carefully.
