We tucked this into our review of the HTC Sensation 4G, but it's worth mentioning on its own. We've talked about how Sense 3.0 appears to be just a little bit faster on the EVO 3D, even though both phones have a dual-core processor running at 1.2GHz. Our bet (and it seems like most of you agree with us) is that the EVO 3D's faster because it has a few hundred extra megabytes of RAM inside. That could well be the case. But remember that there are any number of tweaks that have to be made from one carrier to another -- so the hop from Sprint to T-Mobile could be it, too.
Or if you're into flaming, you could just argue that anything is better on Sprint, period, end of story.
