HTC and T-Mobile US have begun pushing out an over-the-air firmware update for the 8X on the carrier starting yesterday. The update is minor and very specific: “Features audio experience improvements for the Skype application” and bumps the firmware from 1532.20.20004.531 to 1532.20.20008.531.

There’s no word on specifically how this improves Skype or why perhaps others phones won’t be getting this update, which leads us to believe that there was some optimization needed in the previous Portico update that was not present.

Despite its specificity though, it’s still pleasant to see Microsoft, HTC and T-Mobile push out firmware updates seemingly with ease, making sure customers are getting the best possible experience from their Windows Phone.
