Ha, Luca is just a mercenary kid!
He deleted all my posts on WURFL forums after I asked him about the "previous" license (before 2.1). He also requested my "linkedin profile", "email address not from a free mail service, and my FOSS project name). If I do it, then he tells me what the license was used before. Luca, you're going wrong way!
P.S. People who want to use WURFL and do not want to pay to Luca, you can just use WURFL 2.1. It available for all FOSS projects without any limitations (its licenses could not be changed)
