Not knowing how this aspect really works.... I've read that the hardware of the new Pixel phones contains what is necessary for T-Mobile "Band 71" (600 MHZ), even though the phones do not support it now.

1) Is this true?
2) If so, is it possible (Google willing) that Google could update the Pixel 2 phones with software/firmware/etc down the road to actually work with this new T-Mobile band?
