T-Mobile today started to push a 31-megabyte update to the HTC One S. If you don't get it, though, it might not be a big deal. The new version, 2.35.531.10 is only for devices that are on 1.53.531.16 or 1.84.531.4, according to T-Mobile's support site. If you're on 2.235.531.7, as a lot of you are after the update a couple months ago, you're still considered up to date and won't need this version.
If you did get today's update and have found yourself at Android 4.0.4, you can expect fixes for data connection delays and signal fluctuations, Wifi issues, crashes and restarts, e-mail links not opening, screen lag and skipping music.
And if you're still holding out hope for some Jelly Bean action, a little more patience is required.
