HTCSense.com is online and accepting sign-ups from people running both the Desire HD and the Desire Z phones — phones that are running the latest version of the HTC Sense UI. Unfortunately, other Android devices, even those running older versions of HTC’s Sense UI can’t get in.

According to a post at ePrice.com.tw, HTC is planning on letting not only other Android devices in, but Windows Phone 7 as well.

Additionally, if you are running on an HTC Desire currently, if the rumors hold true, HTC will be updating your Sense UI to the new version as early as December 2010.
