well I am very upset about this. according to HTC there are no plans to support the Thunderbolt on htcsense.com. 
we can place the blame on VZW as it is up to them to allow the support from htc.
here is the email I received from HTC:
"Dear _____,
I understand you're inquiring about HTCSense.com features for the Thunderbolt. Unfortunately HTCSense.com is not an included feature of the device and there are no current plans to add this functionality. I do apologize for any confusion and for any inconvenience. Please feel free to contact us again if you have any further questions.
