Back in late December of 2012, T-Mobile rolled out the Portico update for its HTC Windows Phone 8X devices. The carrier has posted a new software update details on the handset’s support page of its official website. The carrier has confirmed the update is now rolling out over-the-air (OTA). The update bumps the firmware version up to 1532.20.20008.531 from 1532.20.20004.531, while the OS version remains at 8.0.10211.204.
The new OTA brings improved audio experience for the Skype application on the HTC 8X handset. No other changes have been included in the changelog by the carrier.
This is a minor update, and you can manually update when it from Phone Update > Check for Updates settings, if you haven’t received the notification on your device yet, asking you to download the update.
