Microsoft detailed some of the hardware aspects of Windows Phone 8.1 earlier today, and now a leaked image is providing an early look at one of the first handsets that will run the new operating system update. Evleaks has posted a photo of Nokias Lumia 630, codenamed Moneypenny, and it clearly shows a Windows Phone device with on-screen buttons. The softkeys, as Microsoft calls them, are primarily designed for low-end Windows Phone 8.1 handsets, and its clear from their presence and the Lumia 630 numbering that this particular device wont be the next flagship handset for Nokia. Its unclear what specifications Nokia is planning for its Lumia 630, but some rumors have suggested it will include a 4-inch screen and 1GB of RAM. Given Microsofts clear moves towards more low-end Windows Phones, its likely that well see a lot more devices running the companys future update with on-screen buttons for navigation.
