HTC’s companion site for all of their new Sense devices – currently the HTC Desire HD and the HTC Desire Z on the Android front – has gone live and is waiting for new and excited Sense users to join up. Unfortunately, most people won’t get the pleasure of using the site to its full potential as the phones best equipped to take advantage of them have yet to be released. Regardless, you can try and sign up now ahead of HTC launching the phones to the public. Andrew from Androinica did just that and put together a nice round-up of features you can expect to see upon being granted access. Head over there now to take a look.
