Just FYI, this is the response I got from the company when I complained about it:
Thank you for your message. Because City ID is preloaded onto the HTC Incredible, it cannot be uninstalled from the device. The way to disable City ID is to select “No” at the end of the free trial, which ends 15 days after you receive the initial free trial notification. If you select “Remind Me Later,” or press the Back or End key (or a similar action) the trial expired message will appear after each incoming call (up to 10 times), so please be sure to select “No” upon the first expiration message to disable City ID.
If you are experiencing a City ID trial notification appearing more than after the fifth incoming call and on the 15th day when your trial expires, it is unusual and unintended behavior of the City ID product. We’d like to verify what you are experiencing and greatly appreciate any additional information you can provide to our team, such as the handset build version and other applications you are running, which will help us to try to reproduce the experience.
Thank you for taking the time to contact us.
Best Regards,
The Cequint Team
