I'd like to announce a FREE webapp that I've just created, CabGen. It allows you to quickly and easily convert your <wap-provisioningdoc> xml configuration file into an installable .cab file. I wanted this functionality for my own apps, so I decided to make it a little more generic and give it to the community! If you don't know what wap-provisioningdoc means, then this probably isn't for you but for those of you who know what it means, I hope this is helpful!
