According to HTC, this last firmware is now ready for AT&T’s One X+ and will start rolling out any day now, bringing along a slew of changes, tweaks and bug fixes.
The exact date is still unknown but we tend to think this will be a short wait. Nothing stops you from checking the firmware updates right now – hop over to Settings -> About phone and take it from there. Once you do find the new software waiting for download, make sure to fully recharge your phone, connect to a fast Wi-Fi hotspot and follow the on-screen procedure. Before you know it, your HTC One X+ will be running Android 4.2.2.
