T-Mobile tried to get the coveted 20 MHz F block where they could, but were out-bid by Verizon Wireless in many regions. They did score F block licenses in the Central and West regions, and they picked up both the D and E block in the Southeast.
That left them with only 10 MHz of AWS spectrum in the Northeast, Great Lakes, and Mississippi Valley regions. That might not be enough for major cities, so they beefed it up with an extra 110 A and C block licenses in urban areas. Their biggest A block wins were in the New York and Chicago areas. Their biggest C block licenses are for Philadelphia, Phoenix, LA, and Seattle. That will give them a whopping 30 MHz of AWS spectrum in New York, Chicago, Phoenix, LA, and Seattle.
