We reported yesterday on the upcoming PR1.1 software update for AT&T Lumia 920 and 820, which was spotted at NaviFirm.
The information is confirmed by an email circulating between AT&T employees, which offers details on the changes included in this maintenance update.
According to this email, “the update will be processed over-the-air (OTA) via a Wi-Fi connection. This software update will improve the experience for a small number of customers who have reported issues with connectivity to Bluetooth devices, including times where an affected device appears to freeze.”
In other news, T-Mobile USA already announced the same software update would arrive on its HTC 8X today, so stay tuned for more info on the matter.
