Searching the WURFL Device Database

The Wireless Universal Resource File (WURFL) is an XML file that acts as a global database of mobile device capabilities. WURFL is an open source project at http://wurfl.sourceforge.net/. The WURFL DB (http://www.wurflpro.com/) is a web-based interface that allows WURFL contributors to add or change device information in the WURFL.

The SDK uses a WURFL module to discover devices based on API support or on physical characteristics such as physical memory size or display size.
