Most phones, you can either accept the updates supplied by whoever made your phone or you just don't get updates.

We've made the WiPhone firmware update system configurable. If you want to host your own firmware you can with very little setup required. Check the video to see how to do it, but basically you just:

• set up an HTTPS enabled web server and put the compiled firmware on it
• put an INI style config file on the same server that can always be found at the same URL. each time you add a new firmware file, update it to hold latest firmware version and what URL to find it at
• in the WiPhone, set the firmware update URL from the default WiPhone firmware update URL to wherever you store your INI file
• enjoy the benefits of running your own firmware update server and completely controlling what software runs on your phone
