So VZW has officially launched Band 4 AWS in select cities. Here is a qoute from a Phonedog article from this morning:
"Verizon says that it's already got a handful of products that support the service, like the iPhone 5s and 5c, Galaxy S 4 and the Droid Mini, Ultra and Maxx. The carrier is also planning to update other Android devices, like the Galaxy Note 3, to support its AWS network. It's expected that almost every Verizon smartphone released from this point on will support its upgraded network.".
So I assume an update from VZW needs to issued for the G2 to have this capability too?
