Mobile development is something I have always wanted to spend some time on. Recently I have been looking at mobile application development. I have found there are a lot applications or tutorials on how to convert your Flash Lite files to sis installers which allow you present your swf files like an application on the main menu of your Symbian based phone.
SWFPack is a on-line service which will package up your swf into sis file with little to no effort. Mind you its still in beta but it does what it promises on the tin. Hell it even lets you add a custom icon which is used on the menu.
