Earlier today, evidence came forward for an unreleased RM-1109 Lumia phone destined for Brazil. Unfortunately, no other information about the device was found except something related to battery size. Speculation suggested it could be the rumored 'Lumia 1330'.

Now, the same site that trekked through Anatel's documents have churned up another record connecting RM-1109 to the unannounced Lumia 640. Janela Tech is reporting that this device is dual SIM and sports integrated digital television (DTV), something that is increasingly popular in that region.

It is currently unknown if the Lumia 640 is an exclusive to Brazil, which seems likely, or another mass-market lower-midrange Lumia. More information about the phone is under embargo at Brazil's regulatory agency, Anatel, until after Mobile World Congress in March. The timing suggests we will hear more about this device during Microsoft's conference. Alternatively, it may only receive a local announcement, due to the smaller market involved.

Regardless, if the thought of a smaller battery for your Lumia 1320 replacement made you upset, you can rest a little more comfortably tonight.

Microsoft will be at Mobile World Congress March 2 through the 5th and Windows Central will be there to cover their announcement.
