Nokia Lumia 1520 phablet is indeed coming to AT&T, just as rumored, under the clever nickname Beastie, judging from a blurry leaked photo of the carrier variant. The international version was strutting its stuff as Bandit not long ago.
Beastie seems to suit the largest WP handset ever right, if we count the speculated 6" Full HD screen, possible quad-core chipset, and a claimed 20 MP camera with PureView Phase 1 oversampling technology and possibly optical image stabilization. There seem to be some subtle differences between the leaked international version and the AT&T variation, though, such as the connector pins on the back, which here are moved at the bottom instead of the top, but it might still be a prototype, so no conclusions are to be made before announcement.
The unveiling and launch seem imminent, so we'd be surprised if you won't be able to snag the Lumia 1520 as a Christmas gift for yourself or someone else.
