14 DAY TRIAL // It looks like Aio Wireless is one of the last network operators to offer the Windows Phone 8 GDR2 update for Nokia Lumia 620.
As WMPoweruser points out, the MVNO operating on AT&T's network has been selling the Lumia 620 for quite a long time, but it did not manage to secure the GDR2 update until now.
AT&T customers who purchased the Lumia 620 had to wait quite a while as well, but Aio Wireless users had to wait even more for GDR2 to arrive on their smartphones.
Also known as Nokia Amber, the GDR2 update brings major features to Lumia 620, including Nokia Glance, FM Radio and better camera UI and apps.
Aio Wireless customers who own the Lumia 620 should expect the next Windows Phone 8 GDR3 update to arrive sometime next year.
