Etwas für die Entwickler (auch Tekkis genannt) unter meinen Lesern ist die XML-Datenbank WURFL von Luca Passani und Andrea Trasatti. Hier kann man zu fast jedem Mobiltelefon herausfinden, welche Funktionalitäten/Features es besitzt.
The main scope of the file is to collect as much information as we can about all the existing mobile devices that access WAP pages so that developers will be able to build better applications and better services for the users.
This project is open-source and is intended for developers working with the WAP and Wireless. All the information listed here has been collected by many different people from many different countries. You are allowed to use WURFL in any of your applications, free or commercial. The only thing required is to make any modification to this file public, following the original spirit and idea of the creators of this project. This will help WURFL to grow better and better every day.
