that's a bit of revisionist history.

t-mobile got a chunk of cash as a result of the merger not going
through, which they used to expand their network.


Prior to the merger being blocked, T-Mo had throun in the towel. T-Mobil
(DE) had signaled it wanted out of US business amd T-Mo (USA) had
stopped investing since it knew its customers would fall onto AT&T's network


no towel was thrown.

Once deal was killed by FCC, T-MO did get cash and spectrum, and that
allowed it to bring itself back to life. But it does not negate the fact
that they had thrown in the towel before, hoping to be bought by AT&T.


it did get a boost from the cash and spectrum but it was hardly dead.

they also refarmed their network so that aws is not required anymore.


The refarming should have been done way before. But wasn't because T-Mo
was expeciting to shutdown its network and move its customers over to
AT&T, at which point, the iPhone would work.


nope.

At time of abandonment, T-Mo had 2G on 1900 and 3g on 1700 (aws). No
LTE.


there was no abandonment.

Once it got the jolt to bring it back to life, the refarming
allowed it to put 3G on 1900 and LTE on 1700.


nope on that too.

t-mobile uses lte bands 2, 4 & 12, which are 1900, 1700 & 700 mhz,
respectively.

note that at&t and verizon also use band 4, the band that's at 1700 mhz.

The big guys lobbied to limit 1700 to LTE. That left T-Mobile as an
orphan trying to put 3G on 1700, limiting equipmnent and handset
support. (hence no iPhone for so long).


nope. t-mobile got aws because it was cheaper.

Once FCC killed AT&T purchase of T-Mo, the iPhone magically became
available for 3G on 1700 (benefiting canadian new entrants who only have
1700) and the influx of spectrum allowed T0Mo to start shifting 3G from
1700 to 1900 so it could start to deploy LTE on 1700.


nope.

But the only reason it didn't do that before was that it was expecting
to shutdown its network so there was no point spending money to refarm
your spectrum if it will be shutdown not long after AT&T signs the deal
on dotted line.


nope. there was no planned shutdown.
