The so-called Portico update for Windows Phone 8 devices is being rolled out internationally after first appearing on the Nokia Lumia 920 and Lumia 820 in the U.S.

The new Portico Update allows for the ability to reject calls with SMS, always on Wi-Fi along with some messaging improvements. In truth, this is same update that has been making the rounds on the HTC 8X since December, so apart from always on Wi-Fi, there's nothing truly exciting here. However, if you're an owner of a Lumia 920, then you'll get some extra love.

This update managed to fix some problems facing Lumia 920 users where the camera is concerned. While the Lumia 920 camera is great at taking low-light images, it fell short when taking daytime images due to blurriness in the picture. The new update apparently fixed this issue, which manages to bring new life into the Lumia 920's camera capabilities.

For those who are awaiting the update but hasn't yet gotten it, note that the full rollout to every market will not be completed until March 2013. That's a long wait for some users,  but the only other option apart from waiting is finding a Portico ROM that is working perfectly for your device.

The boys over at the XDA Developers fourm should have a few ROMs based on Portico, but be warned, completely wiping your phone with a new ROM could brick your device for good. So take this chance at your own risk, don't come complaining to us if your phone blows up in your hands.
