RabbitEars link for the 600 MHz Phase transitions by market. Select each phase number to turn determine which phase number is your market which can be in multiple phases.
For example: Los Angeles market area is broken up into Phase 2 and Phase 3. San Francisco market area is broken up into Phase 8 and Phase 9.
Ensure the pulldown selection is set to Map for Phase on Channel 38-51 for Phase X (where X is which phase you are currently looking at)

EDIT 3/6/2017:
Looks like Tmobile is not wasting any time trying to get the 3GPP to approve a LTE band class for the 600 MHz spectrum. The proposed B71 is in the works with the following Sponsoring members: T-Mobile USA, Ericsson, Intel, Nokia, Qualcomm, Samsung, US Cellular, Skyworks Solutions, Deutsche Telekom, C-Spire, LG with the plan to support 5, 10, 15 and 20 MHz bandwidths.
Surprise surprise that AT&T and Verizon are not present. Lets hope the spec can be finalized by September 2017 and OEM equipment to be out by early 2018.
