While I'm okay with the unlimited high speed, although it's still just in metro areas and could use much more infrastructure to get it up to par with what it should be ... but that's not necessarily the problem at the moment, I'm sure T-Mobile is working on getting more LTE coverage in general.
However, I will give them the benefit of the doubt and assume that I'm probably missing something ... how do you see the amount of Hotspot data you've consumed? If they are going to limit me to 2.5GB, that's fine, but I want to be able to know what they are seeing so I can manage it accordingly.
