answer:You can try a hard reset on your device which will delete all your data on your phone (basically reset it to factory conditions). From the HTC website: A hard reset removes all information from your device and returns it to a state just like it has never been used before. All contacts, messages, emails, 3rd party applications, etc. will need to be reinstalled after performing a hard reset. To perform a hard reset, from the Home screen tap Menu > Settings > Security > Factory data reset. Follow the on-screen prompts to complete. This process will take 5–10 minutes.
