T-Mobile LTE on the Nexus 4?

A while ago, I heard some speculation that T-Mobile's LTE spectrum is actually compatible with the Nexus 4 in the US. Now that T-Mobile has activated it's LTE network in some major markets, has anyone here given it a shot? I know the 4.2.2 update disabled the phone's LTE capabilities but it shouldn't be too hard to go back to 4.2.1. There are also a couple videos on youtube showing LTE working on the Nexus 4 in Canada so it wouldn't be too difficult to imagine this working in the States.
