Since there's still some uncertainty about whether the Gingerbread update for the HTC EVO 4G will include a new version of HTC Sense, the only way for the original EVO to be able to connect to HTCSense.com may be through a custom ROM that includes Sense 2.0 or 2.1 (e.g., myn's Warm Z TwoPointTwo). The EVO won't be getting HTC Sense 3.0 from any official channels—we know that for a fact—but it's still too soon to categorically rule out 2.x.
And what about the EVO's new siblings, the EVO 3D and EVO View 4G? We still don't have legitimate pricing or availability info to sink our teeth into, but HTC has confirmed that the EVO 3D will be able to support it. The still-unreleased Flyer, the View 4G's GSM and 4G-less counterpart, will play nicely with Sense 3.0 too and to that end, it has recently been added to the list of devices supported by HTCSense.com. Sense 3.0 including HTCSense.com may have always been implicitly understood, but the Flyer's appearance in the drop-down menu makes it loud and clear.
Considering the View 4G's similarities, it wouldn't be a stretch to expect to see it listed there eventually. And the EVO 3D shouldn't be too far behind.[HTCSense.com]
