The AT&T version of the HTC One X is now receiving OTA (over the air) software update to version 1.85.502.3. This is the same version that was leaked a couple of weeks back in the form of an RUU (ROM Update Utility.)

Weighing in at 64.55 MB, the new update mainly resolves the Wi-Fi connectivity issue that some users complained about earlier. There is a also a solution to deal with irregular Wi-Fi drop-outs affecting many users.

Here is the full list of changes –

• Wi-Fi Connectivity Improvement - improves operation when a device leaves Wi-Fi coverage.
• Wi-Fi Throughput (Speed Increase)
• AT&T Address Book fixes - Contacts formatting when synced to AAB

Instruction: To update your device, go to Settings – About Phone – Software updates, and tap the button.

However, remember that if you have a rooted device, this update will un-root your phone, so might have to wait a bit longer until a fix comes out for this.
