Remember Amber? That was the last firmware update (along with Update 2) for Lumia Windows Phone 8 devices. Although AT&T and the Lumia 920 was the last big story we covered in regards to its rollout, way back in October, there was still one carrier who was a holdout: Aio Wireless. No surprise that they are a subsidiary of AT&T.
Yes, the Lumia 620 on Aio Wireless, which runs for an amazing $99 on contract, has not had its GDR2 and Amber update. At least not until last night. Nokia and Aio have finally flipped the switch, pushing out the OS and firmware updates, which is now live.
