Hello I was wondering does anyone know when does T-Mobile plan on approving and releasing the Nokia Lumia Black Update (GDR3) for the Nokia Lumia 521 and why is it taking so long to get approved from T-Mobile because Nokia already says its waiting for carrier approval status? AT&T already released there Lumia Black Update about 2-3 weeks ago for the Nokia Lumia 520 on there network and no major issues. I also was just wondering what about the Metro PCS variant of the Nokia Lumia 521 because I know T-Mobile has acquired Metro PCS but I have not heard anyone really talk about the Metro PCS variant and I know this is a T-Mobile forum however I hope it also receives the updates just like the T-Mobile variant one because they are exactly identical besides different carrier?
Thanks
