when you install a new OS, there is an exe program file called Loader in C:\Program Files\Common Files\Research In Motion\AppLoader

i want to study the program file, is there a way i can view & edit it in anyway??

Please let me know any nify programthat might let me edit it?

I would assume that standard developer tools that decompile an application would do what you want. I dont know for sure as I am not a developer.
