We have an issue on N5130, a key image is print over the application icon (forward lock protection).
I can solve this but it works only with unsigned jad...

I made the following changes:

I generate a .dm file from .jar using NMIT (Nokia Mobile Internet Toolkit 4.1). Then i edit the .jad file to point the .dm file instead the .jar and modify the file size length property (we try with the original jar size too).
These changes works fine with UNSIGNED application but fails on SIGNED one (signed with JavaVerified).
When i download the SIGNED version i get 'Application illegally modified' error message and the application doesn't install

Anyone know what's happend?
