Microsoft has kept hands on time with its new Windows Phone 8 devices to minimum. However, recently a finalized build of the Windows Phone 8 SDK has been out (limited) to only handful of developers. A leaked SDK video has been floating around (posted) by WP Central. They said that its not a thorough walkthrough of the upcoming OS but covers “things we noticed immediately.”
At first glance, it doesn’t seem to reveal anything that is not currently present in Windows Phone 7+, haven’t seen or talked about but as WPC points out that it could mean that Microsoft is keeping some things hidden until the final OS is ready for launch. Or probably there isn’t anything else. Whatever is true, we will surely come to know about it in a near future.

Until then feel free to check the above video

Both the Lumia 820 and 920 — expected to be announced at an event in New York September 5^th 2012 — are believed to feature wireless charging, and the evidence grows this morning with the leak of an image showing the models on their charging pad. The pad looks to be nearly as long as the phone itself with a single cord trailing off into the distance (presumably connecting to a USB port), but if rumors of Qi compatibility are true, it’s conceivable that owners of the phone will be able to use a variety of pads from other manufacturers as well; for instance, offers Qi wireless charging on a number of its smartphones.

Nokia originally launched its augmented reality app City Lens back in May, and now the app is finally out of its beta stage. City Lens uses the device's camera to display nearby stores, restaurants and other notable locations in augmented reality style, along with important information about each location — including reviews, directions, hours of operation, and more. And when you're not in the mood to have your reality augmented, you can also check out the same information through both a list and map view.
