I request all the experienced mods to help me on this one. I want to edit .mif files. I want to preview, edit and repack the icons. I have SisContents 1.7.0 build 65. I have no Idea how to open .mif extension file in that. It just doesn't let me open any file except .sis, .sisx. and .ngage. Also tell me how to put jpg file in splash screens. I really like the standard icons of ofw of Nokia 5233. So, I want to make my cfw with those icons. As I can't open those .mif files, I'm unable to edit Splash screens too. Anybody to help me? 

Open siscontent File->New package->Empty package now press to Content and Add entry-> Add file entry and now u can choose mif file If mif file is loaded tap on file and push to View details now u see files inside mif and by editing u can replace every icon

Thanks so much!
