Speculations said that the Nokia Lumia EOS will be in Microsoft Stores by July 22, which means it will be available on store shelves by the later part of the month. A screenshot of a Microsoft Store inventory showed a Nokia device called the 1020 said to be an AT&T exclusive.

The next flagship device, said to be priced $600, will come out in three colours - black, yellow and white. Nokia will roll out of the Lumia EOS next week at the Conversations 2013 event in New York.

Slashgear reported that each Microsoft Store will have an inventory of only 70 units among the three colour choices.

The phone will have a 41-megapixel Pureview camera and include as well an exclusive app called Pro Cam, the same shooter found on its Nokia 808, which however run on the Finnish firm's Symbian OS, while the EOS will have a Windows 8 OS.
