T-Mobile USA's HTC One S is receiving its biggest software update yet today, bringing the aluminum-clad handset up to Android 4.0.4 (from 4.0.3) and HTC Sense 4.1 (from 4.0), according to reports from the Android Central forums. It looks like Tmo's One S is getting the update that was originally pushed to European One S phones just over a month ago, meaning owners can look forward to improvements in phone performance, and a couple of new features like quick settings in the notification dropdown.
According to the changelog in the forums, the update also improves Bluetooth performance, and fixes Wifi connectivity issues that've been affecting some One S users since launch. The update file weighs in at 150MB, so you'll probably want to make sure you're on Wifi before taking the over-the-air package.
