Nokia to unveil Arrow, Phi Windows Phone 8 smartphones on September 5

Nokia is set to announce two Windows Phone 8 smartphones at its September 5 event in New York. The Verge is reporting the two smartphones will be the Arrow and Phi (internal codenames) and will be branded under Nokia’s Lumia range.
The Phi is expected to be the higher-end device, which could be the one that surfaced a few weeks ago. It is expected to be thinner than the Lumia 900 and sport a 4.7-inch display. Microsoft and Nokia are said to unveil the final design on September 5 but it is likely to have the typical polycarbonate casing that is similar to the Lumia 900 and Lumia 800.
The Arrow will be a mid-end smartphone but little is known about it.
