will these mysterious towers ever be updated??

Since I can’t tell where your tower is .. I can’t say whether it would be upgraded soon or not.

I'd recommend placing a call to 611 (T-Mobile) then ask for 'Advanced Technical support team' to find out when the site will be upgraded.  If its in the next ~3 months, they'll tell you.  Of course, often they may have the wrong site and upgrade a different one 'assuming' that's the one you meant.
