After we've seen the RM-877 (possibly the highly anticipated EOS) pass through FCC, the RM-941 has since followed through. The Nokia device passed through with support for AT&T's GSM 850 and 1900 bands and will feature a WVGA display. While we're not seeing LTE capabilities in the US, such frequencies are believed to be included outside these two regions.
The RM-941 is capable of the following: GSM/GPRS/EGPRS900, GSM/GPRS/EGPRS1800, WCDMA900, WCDMA2100, LTE845 (Band 20), LTE1800 (Band 3), and LTE2500 (Band 7), but as noted above this is for those of us who reside outside the US and Canada (possibly the RM-943). Nokia has also included Dual Transfer Mode, a feature that takes advantage of the multi-slot GPRS capability and enables simultaneous transmission of voice and data.
Could the RM-941 and RM-943 be variants of a rumoured Lumia 625? We'll have to wait and see for more details to emerge. One thing is clear, between Samsung, HTC and Nokia, a "refresh" of Windows Phone 8 devices is just over the horizon this summer.
