You may remember that we reported, exactly a month ago, on the appearance of a PR (Product Refresh) 1.1 update for some Nokia Lumia 920 and 820 product codes? It seems that releases will be in bursts at roughly the same time each month, since Nokia has now announced that Microsoft is pushing out a new wave of updates for Nokia's Windows Phone 8 flagships (quote below). There's mention of the rollout being "complete by mid-March", so this should be seen as the next phase of the roll out, which started with North American handsets last month.

It's not yet clear which countries will be getting the update this month, but based on what Nokia said back in December, we still expect a proportion of users will have to wait until late February for the update, depending on SIM-free or network status and the appropriate approval being in place.

Here's what Nokia Discussions had to say about the new rollout:

A Nokia Lumia Windows Phone 8 software update providing performance enhancements for the Nokia Lumia 820 and Nokia Lumia 920 has started rolling out over the air. Delivery will continue in a phased manner over the coming weeks and is expected to be complete by mid-March. You will receive a notification on your phone when the update is available for you to download.

Good stuff. I've been running PR1.1 on my Lumia 920 for the last three weeks and it's a huge improvement, with a camera that lives up to expectations and Wi-fi that (shock, horror) actually stays on.

Comments welcome as and when you receive this update yourself. You can check for updates in Settings on the phone or just plug into the Windows Phone tool on a Windows 7 or 8 computer.

Here's Microsoft change log for the 8.0.10211.204 platform update:

Messaging improvements. A great messaging experience is now even better. You can now add multiple recipients at the same time when you send a text message and automatically save unsent text messages as drafts. You can even edit received text messages before you forward them.

Text replies to incoming calls. Can't take a call? Now you can send a prewritten text reply to a caller directly from the call answer screen. It's a nice way to let people know that you're not ignoring them.

Internet Explorer improvements. You can now change your settings to prevent pictures from downloading automatically—an easy way to help keep data usage low. You can also delete selected sites from your browsing history and leave the rest intact.

Wi-Fi connectivity. Got a favorite Wi-Fi network? Windows Phone 8 will now prioritize Wi-Fi connections based on your connection history.

Other improvements. Includes many other improvements to Windows Phone.
