I have created a .def file. It contains nothing but the string application.
Now i zip the .def and my sis file and rename it to .pip

Now i create a Forward lock .dm file using NMIT 4.1.
While creating the .dm file i specify the Content-type as application/x-pip
and Content-transfer-encoding as binary.

I have added the following MIME type on the server
AddType application/vnd.oma.drm.message .dm
AddType application/vnd.oma.drm.content .dcf
AddType application/vnd.oma.drm.rights+wbxml .drc
AddType application/vnd.oma.drm.rights+xml .dr

Now when i download the .dm file OTA on my 6630. It installs file but then gives an error "Unable to read file!"

So basically everything works...but for no reason i get this error.

Have someone encountered this previously. Please let me know how to reomve this error.
