This tool will report all available header information sent by your phone, including accept-type, x-wap-profile and user-agent strings. The tool will also check this information against several available phone support databases, like WURFL (The Wireless Universal Resource File) and the RUMKIN.com phone support database.
You can use this information to determine what ringtone and video types you can use with your device and how to download them.
