Today, is the big day for AT&T Samsung Focus and LG Quantum Windows Phone owners, as the "NoDo" update start shipping.
You check the phone through the Marketplace or "update my phone" in Settings, you won't get anything, but plugging the phone into the PC via USB cable, firing up Zune software, would immediately show a "Samsung Update" is available.
"Samsung Focus or LG Quantum, will be installing two updates. The first notification you'll see is for the February update. Once you've installed that, you'll be ready for the March update, which includes copy and paste, improved Marketplace search, and faster app launching. Your phone checks for new updates every three days, so be aware that the update notifications might not come right away--or arrive back to back."
After downloading the update, Windows Phone/Zune creates a backup -- it may take a while (depending of course on how much stuff you have on your phone). Next up is "Installing updates", with a progress bar on the phone.
Finally, reboot you device, and you're all good to go!
Once you've installed February, unplug your phone and plug it back it. March should now be ready to install. (This how-to article has more detail.)
