It's been so long I'm on this one !
What ever I do, SIS files generated by Adobe Mobile Packager or SWFPack/Nokia Packager don't want to run on S60 3rd Emulator : "file corrupt"
I tried to fix icon file, file name, file size, phone configuration, etc...I'm still unable to launch anything.
I finally found the answer : the S60 3rd doesn't come with defaut certificates!
Just follow the instructions on this Nokia Technical Solution
