Now, it seems there will be no Lumia 330 and rather RM-1032 and RM-1034 may be called Lumia 532. This has been revealed in Brazilian certification, as RM-1032 is referred as Lumia 532. In markets like China, number 4 is considered unlucky, so Lumia 532 name seems quite logical.
FCC certification reveals that Lumia 532 and Lumia 435 are the same device variants and both will have Single-Sim and Dual-Sim flavours. There may be difference in support of network bands though depending on the markets.
The device may get launched soon as the request confidentiality dates for exterior photos and manual is 30th January.
With its variants already passing certification in Indonesia and at FCC in USA, the 4-inch Lumia device which may have hardware touch-buttons and comes with a 800 x 480 resolution display (confirmed), looks destined for a sooner release. The FCC report also reveals size specs of the device and it seems to have 118.1 x 64.7 mm size, which compares to Lumia 530 size specs of 119.7 x 62.3 mm.
