I have been emailing and this is the response -
Dear Leith,
Thanks for contacting HTC.
We are happy to be of assistance.
Due to the overwhelming response since the release of new HTC phone models we are forced to close the HTCSense.com website temporarily because of heavy traffic.
As of the moment, we are unable to provide a time frame on when it would be fully operational. Rest assured that we are doing our best to restore the services that the website offers.
Should you have any more concern, we are more than happy to contact you at your most convenient time.
You may always call us at 1300 482 482. Our business hours are from 8:00am to 8:00pm Sydney Time, from Mondays to Saturdays and closed on Public Holidays.
Have a nice day!
