After many rumors and accusations T-Mobile provided a means to update Samsung Vibrant Android phones to Froyo on 1/20/2011 (old news for many). After news of the update was announced, I waited a week for the update to be pushed to my phone; nada. I finally did some searching, and found this – the instructions necessary to download the Mini Kies installer, and upgrade my phone. So much for patience being a virtue.
The upgrade went smoothly, and the phone seems faster. As for *why* T-Mobile didn’t push the upgrade OTA – possible reasons include cannibalization of new 4G Android phone sales, and the technical support headache that might have occurred from failed updates on some phones.
