Is this the Nokia Lumia 830?

The Nokia Lumia 920 and 820 may be joined by a mystery device known as the Lumia 830.

Just in case the flagship Nokia Lumia 920, the mid-range Lumia 820 and the wallet-friendly Lumia 510 wasn't enough of a selection for you, leaked images reveal yet another member of the brightly coloured, Microsoft-powered family.
Though details are scarcer than a scarce thing, GSM Arena reports that the Lumia 830 will, in fact, be the Lumia 710's successor and not a modified version of the forthcoming Lumia 820.
However, similar to the current Lumia smartphones and not the old Lumia 710, the Lumia 830 will come with Windows Phone 8 – and it'll be available in a choice of five colours, so your phone can match your curtains if you desire so.
We doubt Nokia will keep the rumoured Lumia 830 name – it would make the range a confusing mess. Let's suggest they call it the Lumia 720 because, you know, that's how the pattern currently works.
