Tera-WURFL detects mobile device capabilities (cell phones, PDAs, BlackBerrys, iPhones). These capabilities include everything from ringtone formats to screen size to java/j2me support. Based on the WURFL project, Tera-WURFL uses PHP and MySQL to provide an extremely high performance database-driven WURFL solution. Current releases include support for xml web services, caching, patching, guided installation, sanity checking and one-thouch updates from the WURFL site. Great for redirecting mobile visitors, determining streaming video capabilities and detecting supported ringtone formats.
