Well…you might get a kick out of this one.
There's a dev on s4gru.com that developed an app for the Sprint users over there called CellularInfo. Thing about it is that it doesn't only work for Sprint.
Here's his repo…
Well, there's a connected employee on the T-Mobile reddit that says my area is scheduled for improvements soon. Even if that doesn't mean Band 12 I'm ok with that. I'm already pulling down 50mbps on a good day and a congested day is around 3mbps down.
I don't really need 120+ down to load Facebook pages faster if you know what I mean. 3 isn't great, but it's useable and so far I can make calls and do what I need to do - I couldn't say the same about Sprint, my previous carrier. At least where I live and work.
