The Lumia 925, or rather its model number (RM-892), has been spotted on the FCC website. The device has been tested with GSM 850 / 1990 frequencies and the image supplied in the filing can't be mistaken for Nokia's latest flagship Windows Phone. This would also fit in nicely with recent news of the handset making its way to T-Mobile next month.
For now there's not much else to go on, but check out the FCC image for a quick tease:
If the listing is indeed the Lumia 925 and recent news holds true, T-Mobile subscribers don't have to wait much longer until the newest Nokia flagship is available for purchase.
