RM-914 aka Lumia 520 which is scheduled to arrive in March globally, has come to FCC with a confidentiality date of 12th April. Which makes us believe that it may be the US variant of Lumia 520 coming to T-Mobile as Lumia 521. If you remember a leaked T-Mobile roadmap then we had a “Nokia Flame” with a date of 24th April.


So, it seems with an announcement date of 12th April the Lumia 521 aka Nokia Flame 4G device will be available at T-Mobile from 24th April.
