I remember a while back when I had my Desire that I wished I could use htsense.com with it, I thought the text forwarding etc was a useful feature that I could have used, anyway it was never available for the Desire, only newer phones. Now I've got a newer phone they've shut htcsense.com down! typical. Did anyone use it and find it useful? It says on the site that a new improved version is on the way so, I hope that I don't go through the same problem I had with the Desire where the phone wasn't supported!
used it briefly, all the features generally had issues, kind of like a beta tbh in the way it worked. Your not missing much now its gone, and im guessing the new version will be a lot better, (couldn't be worse).
Throughout the various HTC device forums, you'll find threads on how poor and temperamental htcsense.com was. I managed to create accounts, but never got any of the functions to work properly. If you're looking for phone tracking stuff and other replacements for what HTCsense.com offered, try lookout.
