AT&T HTC 8X finally gets Portico update
As with the other Portico updates, the HTC 8X will get fixes like options to have WiFi stay connected when the screen shuts off, reject a phone call with a SMS message, save SMS drafts, and select all in SMS, and of course bug fixes for the reboot issues.
And, remember, since WP8 now does OTA updates, you don't have to connect to your computer to get the update. Just make sure you're on WiFi and go to Settings --> Phone Update --> Check For Updates, and follow the instructions. When it's all done just check Settings --> About to confirm your Software Version is 8.0.10211.204.
